I don't get the hate for the new "armor." I like both designs. And besides- Zero got a new body, so I assume that is a legitimate excuse for the slimmer, not as bulky armored Zero in the Z-Series. Sure, some characters changed their appearance due to a change in style, but I don't find anything wrong with any of them.
But onto the drawing, it's very nice. Even though there's plenty of dark spots, I like how you can still see the little details such as the vent on the chest or even some of the most subtle of cracks if you look hard enough.
Though the wires from the back do bug me a bit. Even though there's more light at the top of the picture, it looks very flat without much shading or something, and is really easy to get your eye to look at that than Zero.
