Green Lantern Redesigns I did awhile back, which was posted on the amazing Project:Rooftop
(check out the site if you haven't!). Enjoy y'all!
The whole idea here is about the ring creating the costume, just thought that perhaps the basic outfit (left) should be black with a sort of “galactic camo” (not unlike Starman’s), and the ring builds the overlapping outfit on top of it, depending on the circumstance. We have the standard, more militaristic uniform (middle)- very armor-like with emphasis on the ring hand, while the shoulder on the other side holds a sort of rank, and also a ceremonial outfit (right), for funerals and celebrations on Oa.
