I hate critiques. I always try to take what ever advice is given, but If I've been given a list of things that's wrong with my work, (especially about anatomy) it makes me die a little inside. It's not because I can't conceive of my doing things wrong or anything. I just don't care to have my work picked apart.
That said, I will always offer my work up for critique if I think that it will help at all. I almost never discourage critique of my work either. I hate it, but I'll pretty much always accept it. I try to just grin and bear it.
The absolute most irritating thing for me was to be told stuff about I was doing wrong with anatomy by people with galleries full of photography. I was just all: Wtf, seriously? If they had commented from a gallery full of drawings I would have been, like: okay we're doing the same thing here. It's not like they didn't seem to know stuff, and they were right about things, but I just...Grrr!
It's just that I'd like someone critique my work from an account that has drawings in it. That way I wouldn't wonder if I'm below the notice of people who work in my medium.
