Oh.
My.
God.
That, sir, is one SERIOUSLY bad-@$$ character!!! I can identify the base helmet as Iron Man, a TCW space-armor rebreather, and a fin on top. Can't see the sides well enough to figure out what mods you made there. *In my personal opinion,* I'd put that head on some non-Clone armored body for one seriously mean bounty hunter.
Good work on the other guys, as well, but this one just overwhelmed me. Is his partner's head a trimmed down Clone helmet? Your paint-job makes it almost impossible to tell - and that's a GOOD thing!
