not bad. the skin tone should be a bit more blueish though. i dont like the black outline over the beard, remember that hairs are fibers and should be sticking out from the skin. i suggest you also make the face completely freehanded. very nice wood texture, but the detail is too fine, try to make the wood fibers(?) a bit thicker. i also suggest you make some sort of lighting around the face to make the eyes seem glow.
