Pretty neat, would suggest fading him into darkness, and still seeing a faint silhouette. Would add a bend "arm" frame, and also make the arms in the normal view have hands right now it feels like he has no arms, and then "pop" Arm "bang". Even if his right hand holds the gun in it while down, if you really feel like doing allot of reanimation you can make him reach into his jacket for it.
Nice fade just a tip on small scale like this the viewer cant really see too much "angle" so you can round his head out. :) Even if it was larger I think the sphere shape of the head will still keep the "dome shape" and not angle the side of the head down. :)
In fact the character does not teleport himself, but he just disappears. I would show the side "invisible assassin" of my character, based on the character of the video-game and the movie called "Hitman" ;)
