Another piece i did after watching Aaron Simms's workshop. I used textures from CG Textures.
This is is the best of all of them I think. I like the grain, texture but much of the image is blurred. Sharpen it up with some hard edges to increase definition, especially around the face. Oh, and just the hint of an additional color or two wouldn't hurt.
