You should....
1) .... use your frame rate 20 between 40....
2) .... get some experience before share an animation....
3) .... You not such a bad animator... i was worse than you ;)
4) .... Try to make an animation with Street Fighter 3 sprites :)...
Boring.
If you let it play more than once, the music just loops over itself.
Not enough story
This is basically just a looping fight. Needs a punchline or some plot; anything.
Make the..
old music stop once the loop restarts.
Music looping and sprites
The music looping is a big problem. Also the sprites look a little jittery, like they don't stick to a set path or placement when needed, nice attempt though.
