Here's my CnC ... might be a little rusty 'cause I haven't done this in awhile.
The black line near the text in the lower right-hand corner is distracting from the focal, so I'd suggest maybe putting it on the overlay blending mode? Try that and see if it looks good. That or just take it out ... distraction from the focal is generally a bad thing.
Your effects are pretty nice, but something about the white splotches to the left doesn't seem right. I don't know if you lowered the opacity ... but I see the depth you were looking for. Maybe try to up the opacity, but blur it more. It's just a continuity flaw that makes those stick out from the rest of the smaller splotches on the right. This is a tiny thing, but maybe the lightning ring around him could be blurred some behind him ... to create more depth.
I think the text would've been better on overlay and kinda wrapped around the right side of the lightning ring ... see what I'm saying? Text is good when near the focal, yet keeping the flow.
Hope that helps!
