Her lips are (as the other person mentioned) too darkly colored to belong to a lil' girl, unless she is wearing make-up. ;) Also, her eyes are very far apart. If you'd made them (well, the one we see, anyway) closer to her nose, it might help make her look younger. Anyway. :) I love this picture very much. The color selections and composition just grabbed my attention, and the detail is wonderful. :) It almost looks like a recolored photo. Excellent work. :) Keep it up!

Very pretty.I see nothing wrong with it.However if u wanted it to look like a little girl, you should have made her cheeks rounder and her lips , well it looks like she has lipstick and maybe I'm wrong but I don't think kids where makeup ^_^.
