SKETCHBOOK
I'm sure
any artist will tell you that the majority of time spent drawing
is spent on sketches.This can come in the form of "almost"
finished drawings, loose sketches, and small "thumbnail"
ideas.These are the guts of the final product, the simplest way
of expressing an idea, and sadly(at least for me), these are usually
more successful than the final realized illustration. They are
usually more fun as well.
