Nice spar, Alai.
On your behalf of the spar, you have a really unique style with movements I haven't seen before. I like the way you set up your hits, but, yes, the chest wiggle thing does look strange, but you did it a bit more than once. That doesn't matter, you have very good balance and you stay on your feet mostly, which is good. The thing that gets me is how you maintain your flow. Even when you lose a bit of flow, you gain it back by rotating your body and building momentum. I don't see much stiffness at all. You're hits are very coordinated, but try to put more style into some hits. Very nice job.

Now, as for Brains, his style is also a bit unique, but in this spar, he seemed a bit confused on what he should do next. Some of his his were stiff, like the kick to your head at around frame 890. His recoveries are good when he loses his balance, but he loses his balance a little too often. His hits are really smooth and has some style. He did a good job in this spar as well.

The main lack in this spar is teamwork. You two got a little messy at times. Try to plan each hit, or if your partner is going to hit, tell them whether you want to dodge, take the hit, etc. But, everything was nice and smooth, and it was a good spar. (I don't give ratings :P)

Phew, now that that's done, I've somewhat made a mixture of my tricking replay with my cartwheel replay. (It's a new replay though) The name of this replay represents my laziness in making a pose. -_-
