I really like the blood particle effects. Spend some more time drawing more frames in between keyframes though to smooth out the movement.

Hey! Good job here! You've obviously spent a lot of time on the blood (looks gorgeous... needs a bit of double framing though, it disappears too quickly). The movements aren't bad; the gravity on the first anim was a bit off (he jumped off the wall then fell straight down) and his legs went a bit weird in the jump :D The black guy in the first anim looked pretty good though, nice anticipation for the kick, although he could've eased out of the kick better :)
Second anim: Not much to say! The red's moves are almost spot on, though the kick could have had some easing out... And the blood is fantasmagorical :) Keep it up, looks great so far.

Now, for the first, I had to watch it like 15 times before being aware what happened.
I suggest adding a first frame of them just standing so that the human eye can identify who our characters are.
The red guy also in the air, lacks easing. So he falls too quickly. You can pretty much fix this by double framing/inbetweening the peak of the arc.

The second is nice.
The blood could be there for a bit longer to actually understand what happened without having to watch it a few times..

Basically, they're both good, but too fast and short to understand on the first go.
