Sword of Damocles: Black(/Grey) King

I've been marathoning the anime [K] recently, and felt like designing a few Swords of Damocles of my own just to try my hand at it. This one is the Black King's sword (the black king standing for justice and judgement, which is something like I felt CATHEDRAL kind of did, but not really), so I hope you'll forgive me for taking a few liberties there. Done in ink and colored pencil.
