A few things that might help you get it where you want -- the size and perspective of the stick (it looks weak as not wielding strong, championship work -- this being a caricature you could stand to feature it more), I would do more with the background so it's not so cloud-like, and I would perhaps add some contrast to his head and face to be able to compete with the graphically dominant uniform.

You did a great job again on this too! Excellent the contrast btween the smooth, realistici transitions on the face and the body vs the strong outline.
I also definitely agree on D Akey suggestions since this outcome deserves to be worked up to become perfect.
If You like, perfect, etimologically, from Latin, means something like accomplished, made throughout, from the composed verb per- facio, in the sense of going through all steps to the end; per (across, through in the crossing motion complement). In this sense is a little bit like the similar verb prefix ver in German, i.e taking the verb action up to completion.
