Will just follow Joji's lead.
Walk cycleAh, yeah. I just remembered I've already gave it a cc. MOVING ON
Run cycleI can see you've gone the lazy route with that one, seeing how the origin point doesn't move AT ALL, and the legs are straight up Naruto-ish. You want to try to make it right by giving it the right poses. Make use of
references. They can be anything from your graphical memory to images and videos on the internet.
Broly animationStiff, and lacks the fundamentals. Not much can be said in that regard. Just reread the tutorials. The more you reread, the better.
Ninja-type run cycleUnlike the other run cycle, you did move the origin point this time which is nice, but when it comes to the poses, what exactly has been said about the other one can be said about this one; study the poses of this type of run in an animu.
TestYeah. The same comment is being repeated a third time.
Punch animationWhat made it lack power is its lack of anticipation. Give it some extra frames in the beginning to allow the arm and body to go backwards a bit, then animate your punch, but make it rather snappy. When thinking about anticipation, always consider how does a spring work.
Kick animationEventhough it's a kick animation, the same comment repeats itself a 4th time.
All in all, what Joji said, and with enough time and dedication, you'll make it somewhere.
