The ideas were definitely there!
First off, we have great style and color here. There reds, the tints, shading and such were really well done. Also, the idea wasn't bad. I seriously miss god ole' beatdown toons. The problem here is that this submission is full of what I like to call "flash cheese" to have been so short. Flash cheese is the usage of filters, slow-motion tweens and shading to overcompensate for a lack of actual substance; in your case, that would be actual animation (It looks great in screenshots, but is a bit disappointing in motion). There was VERY little frame-by-frame and action for it to have been a fight, it was mostly just loops and slowmo. If we had just a little more spontaneity, this could be something really fucking sick. Other than that though you seem to know your stuff pretty well, keep working at it, can't wait to see what else you come up with as you get more experience.
