Well Dusty, I did a little edit for you to show you how you could possibly improve the sprite quite a bit. Firstly, your sprite didnt seem to have a valid light source, you had the light on the head coming from the top left corner, than you had light hitting on both sides of the shoulders, so the most important edit I made was I changed the light source to coming almost directly from the top. Second, I editted the head a bit, if youll notice, I moved down the eyes a bit.. In your sprite, it had the appearence the his eyes were looking me directly in the eye, when in turn, they should actually have the appearence that he is looking "forward". But thats basically all I editted.. Hopefully I gave you a better idea on what you can do. Also hope you dont get mad for the edit without asking.
