One thing many beginners as well as more experienced painters have problems with, is how to draw curves accurately.
Curved shapes are important in many paintings, not only in paintings with figures in them, but also if you are trying to capture the gesture of a particular tree, an archway on a bridge, or even a vase like this painting of wildflowers from my garden in a simple glass jar. But if you draw curves inaccurately, your painting will lose something.
Many drawing books concentrate on teaching you to draw curves by following the outline of a curved shape as accurately as you can. This technique is called contour drawing. However there is a major problem with this technique — it is impossible for most people to do this accurately.
Even after many years of practice learning to draw curves accurately and getting them in the correct proportion at the same time is extremely difficult. For most people, including me, it is an impossible task.
But luckily there is a much easier way for how to draw curves accurately. It is called the straight line approximation technique.
In this technique, you approximate every curve by a series of straight line segments. It is much easier to get the proportions of these straight lines accurate. Once you have drawn these straight lines accurately, you can then easily convert them into curves as shown here. This is what you do:
How to draw curves accurately

The great classical master draftsmen, such as Pierre Paul Prudhon, used this technique to draw the complex curves of the human figure. Follow these steps for how to draw curves accurately
Step 1: Draw the straight lines

Simplify each curve and turn it into a straight line. Start a new line every time the curve changes direction by a lot.
Step 2: Smooth the lines into curves

Round off the transitions between the small lines to turn it back into a curve.
If you don’t know how to draw straight lines accurately, see triangulation.

The most comprehensive art instruction I could find anywhere online, and trust me, I had been looking for a long time.

The Virtual Art Academy is simply the most comprehensive art instruction I could find anywhere online, and trust me, I had been looking for a long time.
Even art schools and academies I’ve been exposed to are nowhere near as thorough, VAA is just amazing!
Most paintings I see where the artist clearly has some skill still lack in either the values or notan department, or fall down on composition – it’s baffling that VAA seems to be the only program that goes into detail on this. Therefore, if you are new to painting or an experienced artist, studying with VAA will get you to that next step.
I also find that Barry is always interested in what we students do and is at hand with great advice. Worth every penny, Thank you Barry!!
I’m Richard Robinson …. best online art training available on the internet today

In my opinion Barry has created the best online art training available. I found the Virtual Art Academy course of painting lessons many years ago and was so inspired by it that I contacted the author and got to know him personally.
Two Critical Keys
If you are looking (like I did) for the best painting course available there are two key things you should know about the Virtual Art Academy course which make it stand out above the other online painting courses available today:
1. It’s Comprehensive.
It covers ALL the key painting concepts and then goes further, revealing more and more painting insights. Most courses miss a LOT out – this one doesn’t.
2. It’s easy to understand.
All that information could easily become confusing, but each piece is laid out clearly and concisely using Information Mapping® making it a pleasure to learn.
If you can find another painting course which does these 2 things better, please let me know. As I said, I have been searching for many years and continue to do so, so you could save yourself a lot of precious time and money by joining the Virtual Art Academy today.

A great learning platform

The sky’s the limit

This is a far more superior school than anything I have seen being taught at colleges across the country

I started learning oil painting with VAA from scratch. Just one year later my paintings started to sell

Only online learning program I have ever discovered using a training industry best practice

VAA is the only online learning program I have ever discovered using a training industry best practice of incorporating Knowledge and Skills to support learning a new activity. Every building block (Drawing, Form, Observation, Concept, Notan, Composition, Colour, Brushwork) incorporates a “spiral learning” approach where you are introduced to the Knowledge/Skill at one level and then reintroduced to it again elsewhere in the curriculum. Sure genius.
I’ve attended workshops, read books, and watched YouTube videos — and none of them provide the scaffolded approach to learning the VAA offers. If you are just starting your painting journey, start here. If you are a mid level or advanced painter, start here. There is a sense of community with artists around the globe. You are part of a peer to peer learning process bigger than yourself.
As a result of the VAA, I have been juried into several shows, am represented by a local gallery and have been selling my paintings on a consistent basis. VAA curriculum’s approach will grow your ‘artist’s brush’ and aid you in finding your artistic voice. As your basics improve, your art improves. Henry Hensche said, “There is study and there is performance, and we should not confuse the two, study is done for perceptual development, our performances show us where we are in that development, and we must have both…”. VAA curriculum offers both.
I went through the entire curriculum, did every every exercise, and today review my printed books/exercises on an annual basis to keep myself fresh and ready for my next painting adventure.

comprehensive art education

Since I started the programme I can see improvements in my composition and use of colour

I have been working through the VAA course for over five years and would highly recommend it to anyone wanting to improve their painting. There is a huge amount of information on the site and it is well presented and regularly updated and added to. When other members have commented on work I have posted I have found it really useful. When I review my work over the time since I started the programme I can see improvements in my composition and use of colour.

VAA, the ultimate art course

An excellent foundation on so many aspects of painting

When I got word of the course available through Virtual Art Academy, I was very excited for the opportunity to learn what I never knew about painting. VAA has provided me an excellent foundation on so many aspects of painting. The course is organized very logically, provides great examples, diagrams, thorough explanations and worthwhile assignments. I highly recommend this course to anyone with a desire for an in-depth education of art.
Thank you again, Barry, I love this course Jeanne

It is wild to see how much I am learning in this course!

I retired last year, and decided I wanted to spend my time in retirement learning how to oil paint. But having never painted before, I wasn’t even sure what to look for in an online painting course. However, I did some searches for “Best Online Oil Painting Courses,” and found several references to VAA.
I signed up for VAA’s ongoing Apprentice Program last October (2023), and I am incredibly glad I did! As a beginner, I didn’t know what I didn’t know, but I didn’t have to: VAA has already mapped it all out for me. It starts out with basic, fundamental stuff, but also teaches me the THINKING that goes in the painting: the composition, my color choices, how to consciously select which darks and lights need to be emphasized, etc.
Bottomline, I am learning how to create paintings that have both visual music and poetry, and it is super fun to see my growth! I cannot recommend this course enough!

Fantastic lesson plans, and a vibrant community
The Virtual Art Academy is the perfect art course I’ve been searching for. Barry’s decades of knowledge are condensed into fantastic lesson plans, creating a vibrant community.

Dear sir
These small notes create great interest in painting.
