The image doesn't give any information about your collision polys. The only thing I can see that seems a little off is possibly the placement of the hat on the character. That may just be the style you are going for and not an issue.
Can you give a little more information about the issue you are having. Really, the best way to get help would be to post the project so I can open it and take a look at how it is configured. I would be happy to help you out with your problem.
