Also known as The Dunwall Horror For an entity that's supposed to be neutral, The Outsider looks rather happy to warp the city with the Void.
...That's what's so eerie about him. The Outsider doesn't show how powerful he is in-game (aside from omniscience, and giving Corvo his mark), but something tells me that when he actually uses his real powers, all hell can break loose, and he knows it.
Still, it's an excellent, sinister piece, showing off that The Outsider isn't something to mess with. Nice touch with the crow on his arm (Corvo?) and I love how you marked his hand- like an offering.
