Okay lets see here, not to bad of an animation. You were able to keep all limbs moving in coexisting matter that made the animation okay. Heck I was impressed on the stability you were able to maintain on the black guy. I know for I have problem keeping the head in good matter of location, but you made it feel like it was center origin and kept it smooth and for a fair bit I feel maybe it didn't move at all( in angle wise). The 3D of effect of him doing a spinning kick was quite well done and really smooth.
The problem I have is the over wobbly feel on the grey guy. I feel like i'm watching noodles squiggle back and forth for which it's too loose. There was no shown effect of the hits that he was taken and I felt like I was watching the scene in Kung Fu Master when the musicians fight the husband. You pretty much just let his body absorb the hits like a jello and it really hinder the power of the hits. Then there's that awkward forearm hit to the hit after the jab. It was dampened and just looked like a an odd movement to use to halt the grey guy or what ever he was doing. Then the long drawn out time between the forearm hit and spin kick. When you started into the spin kick it was meh. For fact I feel maybe his feet should of been facing the other way since from the overall spin he kicked with this right leg.
Overall work on toning down the spaghetti movements and give some lengthy animations.
