People have been asking for a thread where feedback on uploads could be obtained. So here it is. I have some reservations about how acrimonious this thread is likely to get, and if it turns into nothing more than a flame-fest, I will lock it.
Rules for those requesting feedback:
#1 - You are not guaranteed feedback. It is entirely voluntary to give it.
#2 - Danbooru may simply not be an appropriate place for your favorite art. If so, accept this and move on.
#3 - Try not to be too thin-skinned,and don't take things personally.
Rules for those giving feedback:
#1 - Give constructive feedback only.
#2 - Refrain from name-calling. Asking people to be thick-skinned doesn't mean you're allowed to be insulting.
