I am in no way an artist or can really nitpick people stuff but a couple things stand out on this for me.

First and foremost; over-all I really like it

With that being said. The render blending into the BG is not good for me at all. It looks like you used an "inner Shadow" or "inner glow" to try and blend them a little but this is not doing it for me, especially in his hair. Also, why the green and bright colors for such a natural color render?

Also seems like you did a "inner shadow" on the entire border of the image with a very large size but small choke. Not crazy about the corners being so dark.

Just some constructive criticism from me, don't take it to heart or anything just a few things that caught my eye as being not a "total" piece.

I actually didn't do any blending on the render just some light paintbrushes. Decided to darken edges to emphasize the flare. Thanks for the critique

Collab with Lost
