Unfortunately for you, I have returned to the Spriters Resource. What? You don't remember me? Of course you don't. So, here you go, a start of a sprite sheet.

First of all, get rid of all the shading. Then, do something about the shape of the hair. After that, give some sense to his trousers.
The colours really aren't good, they lack contrast, they're boring and far too light, especially against the black. Volume is conveyed poorly and the light seems inconsistent: it seems rather calm on his face and intense on his trousers. Keep trying, you'll get there.
