It's alright however I think you are overdoing the outer glow. It looks weird on the assassins shadow and you've pretty much used it on every layer. The background looks low quality also. The arm going around the n is a nice addition however to do this effectively you must create depth with shadows and light etc.
Wow, I see great improvements from your last thread I think that you have definitely improved blending-wise, and it's great that you are using the assassin render to your advantage by covering the "n" with his arm. Like Jack said though, they need to be set up to mesh well. I like that you are using blending effects such as the outer glow function to enhance your piece but I do also think that it is a bit overdone, and it does in a way "cut off" the render from the piece itself. Great job experimenting so far, your improvements are really showing.
