Nice work, Tedd! I like the pose, too. It looks like the sort of thing it should do in Colosseum, the same as Machamp does! :D
I see a little colour leakage here and there (on the tail for example). A white brush or the eraser should correct this with no problem ^_^ You seem to be using layers which is great! The shading looks good, and is in the right places. The only real crit I can make is the colour leakage and that the lines look a bit shaky (if you're drawing freehand, it might be an idea to use the pen or line tool instead). :)
Hope that helps - and keep up the great work! :D
