I like the armour, I'm guessing it and the head are inspired by Mass Effect? The rockets are a neat idea, too. Brickarms has been selling rockets for a while now, but they're only really usable for spare rockets and big gun ammo chains. I like the idea of having rocket heads to stick on the ends of launchers.
With all due respect, I think the rocket launcher could just as easily be built from a telescope, lightsaber hilt and a robot claw (or more accurately, a Brickarms monopod). The size would be a bit different, but I just think it looks too brick-built to buy, rather than actually brick-building it.
P.S. That android head would make a great spray bottle nozzle.
