Assassin's Creed Fanart

I almost never do fanart anymore but I've also been really into Assassin's Creed lately so I thought I'd indulge in a little guilty pleasure. This is a sketch of Ezio that I want to elaborate on, I imagine him jumping from a building in Venice about to turn a guard's face into a kabob.
Now that I look at it, I think I need to push the pose a bit more. . .
