+ The skin is looking decent.
- But: Whats with the Face? This guy needs eyes, teeth etc. Also try to drybrush the fur with a drier brush ( :) ) and with colours which are closer to each other dark brown - middle brown; not dark brown - bone colour). A little blacklining (between torso an belt, boots and legs etc.) would do no harm either. Last but not least use darker green for the base and drybrush it with the green you used!
