She looks about 15-18 to me. Really cute character, excellent job. The blush is wrong though. Try blending it on the apple of her cheeks not near her nose, it looks like she has Roscea. Then turn your opacity down a little bit to blend it. The chin needs to be soften a tad, and her top lip needs to be soften a tad, its a little bit too pointy. Other than that, its great :)
