I...don't care for it.
I hate the pseudo-belt patch things that suffice for a belt at the waist. That's getting waaaaaay too overused, and I think it's a stupid look. Also, the lines that demarcate the boots at the pants, but it all continues on? I don't need seem lines to make it look cool. Jim Lee has ruined that for me.
And the colors, at least in this sketch design, and the foils at the forearms...I am not a fan of. At least PAD made a mention in the interview he'll really miss the original, and that editorial called for this change.
