Boo!
Hehe, anyways.
Would I would like, pretty please.
Is just a picture of a 5' 3'' girl (Whatever that translates to) with brown hair and blue eyes. Her hair goes down just at her upper back, either in layers or in a ponytail. Wearing a cute purple cottony shirt with a pink heart on the chest and, of course, a diaper with some design on it. (Yay not specific!) And she'd be in...whatever setting seems appropriate, if there would be any at all.
And now for the best part...There has never been a picture or drawing of her, EVER.
Therefore, if you draw her, it cannot possibly be off at all.
