love the first image, pretty damn good stuff.... nice metal gear, or possibly extremely light power armor/hardsuit
Second image kinda sucks...
the third pic is much better, works as a merc, combat zone girl, or even a pretty well to do nomad.
Not really sure what to make of the 4rth pic, it looks cool, but the sword or whatever looks wonky, and the "armor" over the left arm looks all kinda of unwieldy and cumbersome without providing any clear benefit, but makes kind of a neat combat zone dweller or nomad, needs some touch up to hide the fact that its a wooden doll.
Baggy pants girl is cool, civie attire for cold weather I guess.
The faces are ok, the first and last being the best while the other 2 just like like pretty poor photoshop jobs. Had skullface guy for a while, always wished we got a complete character out of him, as opposed to just the face.
Blue pads guy.... well the gear looks kind of cool, but he obviously isn;t a pro, as that stuff would make him easier to spot than a 90's gi-joe.
Cyberninja is fucking awesome...
