Don't take it personally. I stopped reviewing over two years ago because most of the artists will rage at any review that doesn't praise it. Heck, I bet if you reviewed "This art is amazing! You are the best artist ever!" for a lot of art, some of those people would respond with "I know"

I hate that.
People need to hear some sort of criticism so they know what they did wrong and then can find a way to improve.
Not just blast the person for criticizing them.

Yea, I admit Ive been harsh, but their responses can be a personal attack and it becomes ridiculously immature. I hate it :(
