I mean, with my comic, I'm doing it largely for the enjoyment factor but I'm also doing it as a way to improve my inking (hence mostly black and white), to improve my art in general and a few other little personal reasons. And since I've got it online I would obviously hope for some positive feedback - we all hope for that no matter what our other motivations, if we show our work to others we are hoping for a little bit of an ego boost.While it certainly sucks to get negative feedback I think that if our motivation is an internal reward it is easier to accept the flaws of our work and that an internal reward is a bit more satisfying than an external reward.
