Well, it's not wrong of him to tell us, is it? I mean, it's something that's better said upfront than hidden, only to be utterly lambasted for it later. To that end, you can't blame him for defending himself, either. How often do you come across people who are civil enough to simply not care? Very seldom, I'll bet.
All that said, I do like your art, Jiyako. I wouldn't exactly call it polished, but I can say you're a lot better with your tablet than I am.
