That's very nice to be honest, mate! I find the fact that you're using like, the worst Pixar film's hero as your subject slightly disturbing.. I mean - really? Use Wall-E or Woody next time!
I like how you've done the shading by the name, and the red letters contrast really well with the grey. If there's one thing I'd change is add a touch more light to the right hand side, and if I'm being really picky, there's a tiny spike which could be cleared up with zoom and a 1pixel brush. Apart from that, for one of your first times - that's great!
