looks good you need to do a little fade brushing or some light gradient work on the shadow borders though itll make it look tons smoother

Looks really nice with the background.

What program are you using? Photoshop R7?

Maybe lighten the top shadow layer, and then change the blending option to multiply, or colour burn, also maybe when you get all the shadows done, try and use gausen blur at the end to smooth things out. I try and use two different shades for shadows, though anime usually only uses one, the two of them adds a little more depth.

Pic looks good btw.
