I Didn't fix the chin, but had a go at a paintover just on a couple of things that I thought could be changed:

-Made the nose defined by adding form rather than just shadow.
-Altered the eyes to look a tad more natural.
-Made him smile a bit more (hey, he's a winner!) and made the teeth look a tad more natural.
- Couple of other minor adjustments.
I realise my edit isn't the best, but I didn't want to spend half an hour on something that you spent 15 minutes on
