This is what I love about raw design material, it's often so much more disturbing and interesting than what we end up with! If the Illusive Man had shown up looking like...well...THAT, his final scene would have had a hell of a lot more impact as he potentially realised what he'd done to himself and his organisation. Also very impressed with the concept design on some of those Reaper units. You don't need to rub down machines with decaying flesh to make them more threatening as enemies.
You hear that, BioWare? Sometimes less IS more. Especially if it's clothing.
