As I've said to others, haters gonna hate, forget 'em. This isn't for them, this for you, and for those that like your work. Those that don't like it can push off.
Don't understand flaming on art you don't like in the first place. I've seen lots if stuff here I don't like, I just move on. People are different, we like different stuff, there's so much on DA I'm sure you can find stuff more your taste if this isn't it.
And yeah, you don't need to put up with crap, so I sure wouldn't blame you for blocking people that are rude!
