More contrasting in the shades maybe, since I would imagine it protrudes past the cliff. Maybe shadow some of the edges a bit. It's just hard to see the face unless you zoom in. ya know?

Thank you!) Do you mean making it different color from rock it's on? Or just make shades/midtones/highlights more contrasting between each other?

That's pretty cool, but the dwarf head is hardly noticeable. Maybe try to add some contrast to it to help it stand out?
