Night Trooper MOC

I've thinking about this small hanger MOC to display a bunch of night troopers for some time and this is what I've created. I modified a portion of the night troopers with dark red and gray pieces like arms, legs, and waist bands to sprinkle in some variance across the troopers. It feels a little crowded to me but I don't have the pieces (or troopers) to blow this out to a 48x48 baseplate size but I'm feeling pretty happy with it for now. I appreciate any recommendations for upgrades or tips...
