Ow... That about sums up my first response to this at 12am.. But after watching it for about 3 minutes its not that bad. I think its an intresting idea you have going there with the arrow, but there are some major flaws in this.

1) What is he sticking to I don't see any wall there, SO i'm asuming he would fall down or keep going... also there are now shadows, thats fine because thsoe can be tricky but it brings down the qaulity..

2) The top, this is where the animation falls apart, it seems like a sezure warning of some sorts with how random they move and they are also from the wrong game and well your missing the timer as well...Hmm. I'm watched it a few times as I typed this. The finishing and Fatality thing.. Um.. Well I don't get it, It's way to random..

3) The good....Yup I'm not just going to bicker.. The Nightwolf motion and Cage going back are pretty smooth and well done minus a slight jump, The blood effects seem pretty good as well, and I like the concept personally.

4) Heres a few ideas. Also a question or 2.. Try to get everything on the same flow and less jumpy. If you have to rip your own sprites from what ever you can, or just edit the sprites to fill in the choppy bits, also try to flow with the game your making it from, example MK3 things with MK3 bars fonts and charaters, I personally don't like seeing MK1 things with MK4 things with MK:DA things.. Question though? Is this a personal style for you, or perhaps still learning?

5)Last but not least.... keep up the work and strive for better and to improve..

Wow that is very jumpy, but u have made alot of progress since ur last animation. They will get better in time hopfully
