Skull

There is a good balance of the dark vs light shading and slight fading shadows around the edges of the picture. However, there are alot of unblended lines, particularly on the surface the skull sits and on the skull itself. Assuming it's on some kind of cloth, soften it up to make it look that way. I see this was done in some spots, but not in all of them. The cracks in the skull are hard to make, but one of them looks like they are sitting over the surface and not running through it because of the white lines running next to the dark lines. The eyes look good, as well as the nose because you really see the depth of the surfaces. The ridge between the eye and side of the head should be wider though.
