I agree with Oblivion, I see so much potential in you. The moves that you actually go and pull of is just amazing, And that it is twitchy and slightly robotic is pretty much the only thing you need improving forwards in time. But a tip, Don't sit with going for it to much right now, Get going with doing these kinda things like you do.Get a large storage of moves wich you later on can work with to improve with flow and realism.

For the last replay, You immitated King just spot on, No words for that.
For blackwidow. Those grapling moves are simply sick, Blew my mind.
Looks stylish.It's awesome setups towards the moves. the only negative thing about your replays is the slight roboticness. Otherwise i would really really agree with oblivion on that you are one really promising replay maker towards the future.
Looking forward to seing more of your work and seing the improvements on this.

Going to drop by and coment on so much i can to help out.
