Great looking character. Looks like a baaaad man! Perhaps it's because there's nothing around him for scale comparison, perhaps he's just thick with muscle but there's something about the proportions here that make him look short to me or is that by intent?
He does not look like a happy man. And what is it with assassins and sais, anyway?
Cool character design, though I'm not a fan of the enormous Nightwing 1984 collar. And the character generally looks arguably a bit too similar to Mr. Grayson, come to think of it.
