I LOVE IT. He actually looks like, hey, HE WAS DAMAGED and had to be cobbled back together again with metal parts--most designs just make him look cool. It's not as smooth as I'm used to seeing and I love that about this design.
As a black man who has been pissed of that DC hasn't done a redesign of Cyborg's look .... I look at this and I am muted .... Good work man!" Not only does it look awesome, but Cyborg definitely has an imposing presence that he doesn't get to have in the DCU.
I like how you toned down the shine of all that metal, except by the blue light for obvious reasons. He appears more battle ready this way than if his metal was shiny and bright. Excellent work, as always.
