Love the George Patton idea... looks great! Might steal you idea for my Imperial Guard army, although that would look a bit more like a German trenchcoat (insiration for my paint scheme is Waffen SS-> Michael Wittman, 1st SS Panzer: greatest tank commander ever). This does NOT mean that I favour the SS in any way! Tactically and practically they were just far superior to the Americans...
Well, imho the Terminator's Power Fist looks terribly oversized, as the shoulder parts do as well.
And, what in my oppinion is worst: the cigar. Wouldn't such a huge thing kill him instantly? :-D
But your paintjob is quite good, that's why I give you a 5.
