The running's off. Pretty drastically, but I can't quite pinpoint it. I think it's either hovering too long, switching too fast for the style, or not stretching enough at the peak of the stride. Or a combination of the three.
On the "Ladder" the walk was very poor for someone of your ability. It had no flow to it. You need to be moving the leg backwards already before it hits the ground so that the strides merge seemlessly together. The stride length wasn't long enough either.
I thought the block fell a bit quick without enough bounce too.
Also, the letters were shakey.
The "Sword Spin" was nice, although the front foot placement was off by a pixel just at the beginning and ideally he would have pivoted on the front of his foot raising the heel slightly.
"Tactical Breach" was pretty good, although there wasn't much movement apart from what the camera did. Why did the third guy eject a cartridge before they'd started doing anything?
I love "Flippy". The style on that one is absolutely awesome. It's my favourite out of all of them, even if the physics was off slightly in terms of lost momentum during the slow motion part of the second jump.
"Bullseye" was pretty mediocre. I didn't think the effect was as good as it could be. I also think you know full well what was wrong with it and you don't really need me to tell you.
That's basically all the bad stuff I could see. Overall, you're pretty good. It's some nice work there.
