We Got Us an Artist
Your art is amazing, nothing to say against that. The servo/module noises when he moved his arms and such were a nice touch that gave it a little more life.
HOWEVER. And it only looks like a bit however, it's not really, detracted just a point for it:
I've seen this sort of thing before. Not nearly as much as some other concepts, but this reflected a part from the Buu saga in Dragonball Z where they're struggling through Buu's body and Buu has to turn his focus inside himself to deal with them. He's even perched in the open like Black Ace/Spoiler is in this.
I would have clipped two points for what felt awkwardly like a recycled idea, but you got that point back in a few good ways:
1) You made it exciting.
2) It didn't even take one half-hour chunk. The DBZ one took about 10 episodes to go through (that doesn't shock anybody, it really shouldn't) and yours took 5 minutes. I salute you.
All in all, if only for the beautiful action and art, I really want to see you progress in the new OCT. 5/5, 9/10.
P.S... you got pitted against Chimbley before? Nice.
