I like the sound of it, and the ideas of what's going in, but maybe just a couple of things about the GUI itself could be altered. It somehow feels rather...clustered up there at the top, it creates the impression of an awful lot of small units clustered together. I'd personally probably bring some of those things down to the bottom (maybe the head, and the gun). Or, if you're going for the 90's style, maybe put all of those things into an opaque bar, make it look more like they're all part of the same unit.
Still, it probably feels different when it's being played in a game. Nice concept you've got!
