I prefer Number3: Number 1's hands don't seem to display much texture/bump, and the left hand looks kinda wierdly shaped. Also, in Number 1, some portions of the blood trickle don't look as though the same lighting/shadowing in the scene was applied to it. Number 2 isn't that much different from Number 3 (at first glance) but upon closer observation, I think the granite effect gives #3 more realism. Could you reduce the granite on his forehead but keep the granite on the rest of the face? Just my (subjective) opinions!
