My imperials are meant to have that Eastern European/German feel that the film's Imperials somewhat had. The flared out helmet has a more Prussian spiked helmet. A modified gas mask replaces his fierce angular face mask. The dark patina chest armor is a homage to his classic shinny black armor. The clunky weapon is connected to a power pack via the tube.
One of your best works, very nicely done! And I love his clothes, each part looks like something from the original. The jacket reminds of the cloak, the chest armor looks like his chest... computer.... thing.... and the lower part of the chest armor reminds me of his belt, with its many buttons and accessories. Very good job!
I can just imagine it now an "Iron" Destroyer hunting down the fleeing blockade runner at full speed firing its cannon's destoying the engines bording the craft blow torching the doors and stormtroopers killing the defenders and lord Vaders marches in to seize the princess
It fits so well this version of Vader!
