Too slow, if you're drawing a sword chances are you should be going for it FAST so you don't die!
Remove some of the intermediary frames and try to remove the odd bounce save for a couple frames, he should only really go down as he swings his sword towards the camera unless he's a character in a rhythm game I think. You also need to make his knees BEND, shift his feet! Don't just shift his knees, legs don't work that way and it looks like his legs are changing chape rather than moving.
The shield needs to be more stable or the readjustment he does more defined, the shading changes for a couple frames and I'm not sure why. Might be a better look to just move the shield in a small circle and shift the arm a bit as it moves.
The chainmail looks like tinfoil right now with how it creases and folds, might help to put some work into crosshatching that instead of normal shirt shading to give it that linked texture.
Here's a few samples I whipped up, there's a lot of ways to go about chain texturing ranging from simplistic on to more abstract looks:
The first and second are pretty similar but achieve different effects through the shading, with the first looking more "chainmail" and the other looking more like "scale mail". The last one is a different style altogether, using some copy-pasted circles linked together to create a sort of mottled appearance, which would fit with how chainmail behaves with light.
Finally, try to match the hips with the legs. He looks kind of like he has no waist, but you can fix that by straightening out the lines between the skirt and the mail to link up straighter.
