Honestly, I wouldn't mind the nerd set too much if it wasn't for the shorts and shirt. It really doesn't look like an apocalypse nerd, he's wearing shorts and a t-shirt, but this is going to be heavy armor. I don't mind the gear pouches too much, they could look pretty nice. It just looks kind of dinky, and not in a good or endearing way. It's almost a bit too over the top. Throw some jeans under those kneepads, replace the shirt, it'd be a lot better imo. It looks almost cartoonish. Not a fan, when quite a few of the other sets are super sick and make sense this one really sticks out.
I'm kind of surprised that they haven't seemed to change or iterate on any of the armor designs at all from when they were previewed. Could be wrong, its been a while.
At least give him proper pants and protective gear, this doesn't look much like heavy armor outside of the fallout head cage thing. I think that'd make the design better while not completely remaking it.
Not meaning to be rude here, sorry.
