Nice sig. However the only effects I see are on the bottom right
If I were you, I would add some effects on the left side, mainly around his arm.
You should also add something that blends to the background, then blur it to give it depth.

This is pretty cool,
From what everybody else as said there not much more that can be reccomended, however could I suggest trying to make a bit of depth.
