So, i really like the wing design in d, i think it's quite unique. but i like the armor of b the most, the pauldrons really speak to me, y'know? also it looks like it would make a good light source, lighting up both sides of a helmet giving a definite "badger" portrait lighting, which is what movies use to make things look dramatic, masculine, and fierce, which can also work for a angelic hero with the right environmental context.
keep up the good work!
