Great! I like it

Very BareBones Beginner. You lack fundamentals. You're movements are stiff and awkward, most time shaky. you should stick with simple tests and read up on some Shuniu/TheDarkDemon/Zed's tutorials.

Its kinda fast and choppy. Also like mizu said you need to work on basics more like easing and flow.
The green guy lacks a lot of anticipation in his attacks (that were visible). Also its kinda lazy to indicate movements with badly made speed effects, you should at least show the him executing the attacks or whatever he was doing.
Also the reactions on the victim were very bad. Is he a dummy or something? If not he didn't really show much pain. It just looked like he was being tossed and pushed.

I know, i know. i'm NOT a pro.
I got enough time to improve.
Just wait.
Oh, and Pox, the brown one was a dummy...

Doesn't matter, basics are basics. Being a dummy doesn't mean you should half ass animate it. But what he could have meant was that the dummy didn't show any force, the hits looked weak.
