I would. Well, technically, I already do. I think that it's important to tell your friends if there's something wrong with their art because it helps them grow as an artist as well as gives them trust in you as a critic to tell them when something is wrong. X3
Yeah, its constructive criticism (my friends give me that a lot, even though there say I did a good job, they tell me what I might need to improve on). Its not like you're saying "Your art sucks!" or something.
No; I think that drawings are-- personal, shall we say? Like, I know my drawings suck, and I wouldn't mind if somebody pointed it out to me flaws if I had asked. But really, if I don't ask, I would get kinda ticked off. Most of the time, my friends just show me their drawings without asking for comments or critques. .. That's how I see it anyways. I'm a very independent person (.. at times.. >> ) so I would rather get better on my own, y'know? So treat others how you want to be treated, yo. </lame>
