Cybrog looks like some rapper gone mad! sick! i like how chilly he looks, he's pretty normal looking around the the other four witch enhance he needs for acceptance in society.
I love starfire design, it's as trendy as she's made in the show with a hint of uncertainty that stir from her, she also seems to be involved more in the electronice side of the world, who's a better sttling point for her.
Robin looks like so badass comando, i like his gigs, althought he's the one who's not so into the mix as he's he one who looks more hero-ish, he also seem to be less open and more violent somehow.
i find myself conflictive around BB (he's my fav so you see whre this is going) while i can dig his carefree style of barely wearing anything i think he's into overdoing things, i beliave he'll go with making his as flashy as he can wearing all kind of drags, and i feel he'll go and take from several styles such as Emo, pop, swag and more since he's like that, a attention whore (truth is the truth)
Raven design is my favory by far, she looks so... trendy yet so outwanted, as if she wears only cuz she digs it as a whole not to express anything, you retaind the red pearled belt witch is a great touch for nostalgia.
All of them are brilliant and so well designed. not saying art style, the whole gorillaz vibe it's amazing, also the unique palet and the use for hot over cold it's trilling. even thou most character tend to wear more of the cold palet side of the paint.
