The animation was about as good as you can get. Myabe the movements could have been more fluent, but c'mon, its a wombat!
I'm australian, I know they can't move :D
For a first timer this is excellent, sound was good, maybe the whole thing was just a bit short.
If you had have had a scrolling textual story before hand, that was all commical and satirical like actual mortal kombat and then incorporated some special moves into the fight it might have given it some more body.
No big points for criticism though.
It is clear you put a lot of work into this.
