Wow that looks amazing Penny. I'm not a big avatar myself, im a guy and actually only 5'5 in RL as well, and the avatar height scale in edit doesn't even go that low,lol so i made my av slightly bigger than the real me. But it's all a matter of personal choice like many have already said. But i love realism in virtual worlds, the more realistic it is, the more i'm fascinated with it, to me realistic looks far better than over sized anything. So yes if you love realistic sized things stick with them, don't let anyone change your mind, and be who you want to be, if others don't like it, that's their problem not yours :matte-motes-wink:
BTW I have had a few comments for being small myself, like midget and hobbit and some have called me an oompa loompa at times, lol but for me its like water off a ducks back, i don't let it bother me, and i certainly wouldn't let it change my mind into being bigger either. We all come in different shapes and sizes in SL like we do in RL, and there will always be discrimination of some kind by someone, but they are mostly the bullies that pick on people, nice people leave you alone and accept you for who you want to be.
