Need help to improve sprite

[snorsorbet]

You need to highlight the beard and make it look more like a beard... Right now it looks like a necklace. You could try to do that by making the beard expand towards his mouth.

The outlines for the arms look pixelated, try mixing the shade of the arm with gradually more black towards the edges (like you did on the pants).

You could make the pants end a bit earlier than they do right now, but that is not really nescessary.
