First of all, i say lol to the people who say the lightning doesn't fit, and thats all i'll say to them.
First of all the depth is good, it's not the best depth pieces i've seen from you, but it's still nice. You seem to be blurring all of the background still, and in my opinion that takes away from the great depth this piece could have, makes a selection of everything on the background, but leave about 5-10 pixels around the render unblurred. Also never blur the lighting parts of the signature, which in this case you have. The lightning streaks are your main light source, and they seem overblurred in my opinion. Sharpen the lightning streak up that are closer to the main lighting on them, so aka the one that leads onto his hand, sharpen the lighting on the hand, then as it goes off into the distance, blur it the further away it is, so it adds to the depth. Without the lightning though, this piece would look so plain and boring in my opinion, it adds some nice contrast. The purple is offputting and really random. As is that random ass red circle to the right of the render. Looks like your trying to bring more attention to that part of the signature, and needs to be removed in my opinion.

I know I can't beat Anecdote's CnC, but here it goes.
The splatter on the right of the guy doesn't seem like it flows well to me, the purple is still pretty random and kind of off-putting in version 2 and the 'lightning' could be more spread instead of just one side.
