I love the intensity of the picture. The pose and the look in the eyes gives the piece all it needs to scream Assassin!
The costume from what I can see is well done and looks worn down like its seen a lot of wear and tear-it gives it that realistic effect. The make-up is good as well, very simple and effective. The person in the photo does not need a background to project the emotion. I also love the lighting in this piece, it hits at just the right angle so it gives us viewers a "glimpse" of the lovely Assassin's face-just how we all know those Assassin's love to hide in the shadows.
Overall, it's a damn good piece.
