I definitely see an improvement. I remember a previous animation where a wolf was chasing a guy and this one is more nuanced and has better camera work. There are still some timing issues so the characters’ movements are lacking a bit of weight and force. Each punch and kick are the same speed all the way through so they appear kind of “floaty” and lack emphasis. You're headed in the right direction and I see that you've added some dust fx too. Next up, motion blur. Keep going!

P.S.
A decent USB condenser mic and a pop filter (or shield\guard same thing) is a good starter if you’re doing your own voice work. Better quality sound and words with "b" and "p" won't send sharp gusts of breath into the recording.
