is he supposed to be a humorous character? he has one big belly but I dont know how intentional that is. I'm gonna asume it is and reccomend you to not be so shy with your highlights and go ahead and put quite a bit of them on his belly (preferably towards the botton, or halfway down to show how far his midsection is sticking out) to emphasize his bulgous sillouethe.
There's an issue with the way you used your highlights making the chest so bright, and then the shoulderpads so darkened, specially since you used banding on the chest highlights. Try to take that harsh highlight away from the shoulders when you do what I suggested, hopefully that will fix the issue.
I can see what you were going for with using that dark blue shade for a skin and red-headress shadow, but it doesnt really work and it looks cheap. I suggest you use purple, and then adapt the midtones to have a bit of a purple tinge to them. it will give both materials a sense of having reflected light on them.
You got a humurous little fellow there, if all of your graphics have that kind of charm you'll have a pretty neato looking little game.
