Hmmm, never looked at her that way, I guess the lines and dimples around her face do make her look a bit older. Wasn't really consciously designed that way, although I do tend to instinctively imagine her a teeny bit older than the canon 19 or 20 years, maybe 25 or so.
I normally do put all manners of pasties and tassels and such on breasts that I draw, but not this time, those are supposed to be the areola. I'm ok with them being a bit unnaturally evenly circular, but yeah, guess they could use a little texturing/detailing to lessen the effect.
