First, let me preface this by saying anonymous comments are cowardly. I hates them, my precious. If you’ve got something so very snarky to say that you can’t put your name on it, EFF YOU, chicken sh*t. *ahem* That being said, I’ve never received an anonymous comment. :D I wonder why?
A perfectly lovely, bright, generous on-line artist bud-of-mine got a perfectly asinine anonymous comment: “So you draw over pictures. Quite obviously. WELL DONE. What talent you fucking have.”
Clearly, stupid mystery commenter is stupid. Artists, since the advent of photography, have traced over photos to get general proportions, and then re-sketched over the rough linework to create their own interpretation of things. Norman Rockwell. Maxfield Parrish. Donato Giancola. Me. Just to name a few.
Do NOT think that artists always sketch over photos, though. We also draw freehand, work from life, study anatomy, doodle cartoons, exaggerate gestures for emphasis and emotion. How DARE you rake us over the coals for looking at a photo?
