Drawing to communicate concepts
This might unnerve a few people, but let me confess this: when I draw, I'm not necessarily interested in photorealism. Often what compels me to draw is not a desire to dazzle people with realism so much as a desire to communicate certain concepts (for example, what characters from my stories look like). I think I picked this attitude up from creative writing; competent writers are generally less interested in impressing readers with flowery prose than in clearly getting a point across. Of course some basic drawing skills are needed for any representational artwork to be intelligible, but as long as my viewers know what they're looking at and like the concepts behind my drawings, I'm satisfied.
Is this the wrong attitude to have about art?
