I would have a much greater esteem for him if he actually took the time to use those criticisms as an opportunity to improve his actual work, which, aside from learning how to draw feet, he hasn't done in any way. If you hear people consistently pointing out the things in your work that DON'T work, and your response is to keep doing those things, then you're basically making a very conscious, ego-driven choice to say "fuck you" to everyone who's pointing out your artistic flaws, which puts you squarely in the territory of Laurell K. Hamilton.
