i thing the belly and inside of arms is too yellow. the 2colour scheme assumes that the more delicate skin has less pigment. that is, it should be lighter than the rest of body, but not of other colour. the other thing is that the dark (should i say black) parts of the body are too little highlighted. maybe it should be worked up with grey for stonish tone, or brown for more natural skin tone. otherwise, the saliva dropping of his mouth is great!
