When you're outlining, you should use a dark pen instead of using a pencil to enhance the lines. That way, it'll look much cleaner, and it might prevent smearing. Also, try to make the whole character proportional. His head looks a little bigger than his body. o_O The shading is better is this drawing, looks smoother. But yeah, you're improving loads! I think my only complaint is the outlining. Waaah.. so many stray lines. >< Build on the criticism! I can't wait to see your next masterpiece. ^^;;
Oh yeah-- another advice you might want to try; color! Black and white is good, but it sometimes gets boring. @__@;;
