I don't really have a preference for appearance, I think real would work better but if all you have is anime that's totally cool too. Age limits are don't be unreasonable, so don't have a character that's 5 that is an expert at anything, because that's just unrealistic and shatters suspension of disbelief. But I don't really want anyone to be tied down by a specific age limit.

As an aside, if anyone knows why centering just doesn't seem to be working for me, that'd be great :P
