Is your bump map and texture map for the body the same size as the head? For best results, you should make the body maps about twice the size of the head map. That's why there's a noticeable graininess to the body compared to the head - it has a lot more area to cover so it get stretched out. You might want to add a touch of deeper blue in the check hollows for more color depth. Otherwise, the texture is quite nice. Cheers!
