If your friends said bad things about this cute thing, then they're not very good friends. A lot of people would give their right hand to draw like this.
i know what you mean, i draw anything remotely erotic and suddenly its p_rn. i can't imagine what artists like loenardo went through with stuff like the statue of david. people were even more uptight back then. eh well, most of the time other artists have your back anyway! ;P
