I admire your enthusiasm, but you may want to look up the "12 basic principles of animation". I say this not to discourage you though. Your animation is lacking the majority of the fundamentals, and would be much improved by them. minyos.its.rmit.edu.au/aim/a_n…

For instance, your character has to anticipation in his jump. His knees don't bend. The body seems too rigid, and doesn't have actual movement. You are lacking in the slowing in and slowing out, as well.
You do have squash and stretch, which is good. The facial expessions could also use some more exaggeration. Other than that, a good attempt.

You're a good animator; I have a lot of respect for your ambition! But don't spread yourself too thin on this project. Use GoAnimate. The work will go by much quicker that way.
