not a bad start
For a first it's not too bad, I'ld just suggest adding some fighting music in the background. It's short though and it would have been better to add more before submitting because it doesn't really give us much to give advice on except for "it should be longer". So keep working on the overall speed of the animation cause there was standing around which isn't good to see in a fight, and you might want to find a way to clean up the sprites a bit because I notice small blue or green blocks popping up around certain sprite animations. nice try, just keep practicing.
