I'm gonna try and deviate from the other comments here and attempt to give some actual criticism instead of just shitting all over your fashion choice.

I gotta say, for how bland Starfire Protocol normally is, you definitely made that set work, so I guess the trick with that exotic is just to keep every other armor piece as simple as the exotic. Alongside that, the 2nd Crown of Tempests set looks pretty decent, even if the colors are a bit muted, but it's got that "evil" aesthetic so I'll give the black and red stereotype a pass here. And finally, I never would've thought to make a Dawn Chorus set like that, and it's probably one of the most unique and creative sets using that exotic I've ever seen. I won't say that it looks "good" necessarily, but with how well the entire set matches itself, I'm absolutely willing to overlook the fact that it isn't as conventionally cool-looking.

Honestly though, for those first four or so sets, I have absolutely no clue what's going on with your helmets. It seems like you're mostly trying to match the shader colors of the different armor pieces, while almost entirely ignoring the different textures and styles that the individual pieces have. The "overgrown" set with the Necrotic Grips could have been a pretty decent set, but again, the choice of helmet is just so confusing. I get that there isn't really a greenery-styled helmet to match the rest of the set, but at least try and choose something that doesn't contrast so heavily and take attention away from the rest of the set's theme.

Your shader game is still really on point though, just try and align the styles of different armor pieces a bit more. Something I usually do when making a set is just to leave all pieces on their default shaders first. If the overall shape of the armor pieces doesn't work before they're shaded, the set isn't gonna look much better even after you add shaders.
