Although the character design is pretty good, the background is lacking terribly. I think you can spend some more time on it and make it just as cool as the creature. Maybe removing the pencil lines behind it (or what looks like them) would be an improvement.
Also, I can't help but think this is more suited for CHoW, AKA Character of the Week. The abominal snowman looks like a man with no head and cut off at the knees, with a lot of fur. You can see the defined biceps nd clear shpe of the torso. As stated in the CoW rules, the creature it not supposed to bear any human resemblance.
Rules aside, the actual creature looks cool. You did a swell job on the fur and the face has a great expression. Keep it up.
