Wow, what a scene! You did a really really well detailed job, Nick!
So, Luna basically was caught and put in the tube to become a super strong cyborg?
I love the glow of the green nanomachines and the outline of Luna's body in the tube, not to mention the "fan-service" part showing that she lost part of her clothes in battle.
This artwork makes you think about sort of the "before" and "after" parts of her getting caught. Nice juxtaposition, meaning awesome side by side contrast.
I would have went ahead and given her tube-version nipples just to make her more distinctly human, but mink actually put more detail into this than I described as it is (I just asked for "veiled outline of naked chick") and that's really cool, so the slightly odd anatomy doesn't really bother me.
