I have made a discovery.
Many of the artists that i really love and find inspiring with a 3Dimensional and dynamic quality to their work did not study fine art or illustration. They studied animation.
In animation, it is essential to understand the basic (though very complex) movement and anatomy of the body in order to be able to animate it. Although this is also useful for fine artists and illustrators, it is not always essential (I personally find it highly important) These animators are able to think of the subject/figure they are drawing from all angles resulting in a very dynamic and 3 dimensional quality to their work.
This has started me thinking in a new direction…
Examples of this: Claire Wendling, Craig Davison and Kim Jung Gi are three among many.
