What a cute shot (and, I'm sure a precious moment). The photo has a high level of graininess - especially noticeable in the girl's face, shirt, pants, and background at the left of the photo. This really, really hurts the quality of this photo. Many digitals (Fuji is especially naughty about this) crank the ISO up way high automatically (like ISO-1600 or ISO-3200) to allow you to shoot in lower light - at the expense of photo quality. When you sharpen, it only makes it worse.
