I love this one as well.
I'll say it again: I think Warren has been quite lucky on the costume departments. If we ignore the costume designed by Jean in late Silver Age and the Champions, which were... colourful, to say the least, all the rest was quite fine. AUs included (look at Mutant X's The Fallen, for example). Even in videogames where he gets his costume redesigned/modified, he looks fine (will share pics if you want).
Anyway.
I'm not know this was a coloring/drawing error (I'm looking at Extermination and it was different) but this version seen in Jean Grey #1 last year:
Edit.
I don't dislike the memoryless!Warren costume either, but I agree that something is off with it. Might be the metal wings, or the long hair.
