Dear god...
Someone please gouge out my eyes. I hate being brutal like this, but that sucked fat cock. The animation was horrible, the sticks were badly drawn, the effects were nothing more than circles with gradients. Watch some things by Terkoiz, see how he does it. Spend a lot more time on things like this too. Also, make sure that the sound effects match the action. A lot of the time I noticed a sound effect playing and everyone just standing still. Practice, practice, and practice some more. You'll get better eventually.
TL;DR
That was horrible, keep working. You'll get better soon.
