Not bad. I think there are a couple things that should be fixed. First, the nostrils stick out too much. With a piece this small, nostril would be smaller than 1 pixel, in other words, non-existant. Also, from strait on, you usually don't see nostils. Also, the eyebrows make him look very angry cave man ish. Lastly, just add some hair.You also may want to play around with the pants's colors, they are a bit too similar(add contrast).
