My main critique would be to pick a direction for your light to be coming from. Right now you have generic shadows being cast down. Imagine the light is in a specific place and try to shadow from where the light would hit and the shadows would actually fall. On the whole the coloring is good, I think the directional element would help a lot though.
Also, there is no shadow on the hands or neck, which makes them look very flat compared to the rest of the image.
