Mostly just a silhouette right now, but it fits the concept of the character. He's the ultimate member of the Dark Brotherhood (from Skyrim). He lurks in the shadows and kills silently with his Enchanted Daedric Bow. His off hand is casting a spell of invisibility, for added stealth. I will ad some color, mostly dark reds and muted browns, but he will mostly don black.
Did I mention he's a VAMPIRE! Hellz yeah. What better Assassin than a damn VAMPIRE!! Muahahahaha.
The inspiration here is the Nightingale armor and a blend of Daedric armor for that vampire look.
