Welcome back

Chaos is best one, but i think you could improve on it.
The render needs some more blending and some darker hues. Use durn and dodge tool on him to add that darker look.
It would greatly improve the constrast in the piece and appeal.
Effects are good as well as the background.
No text is better because if you're aren't really gonna treat the text as if it's another sig, then don't do it. In other words, using the text tool and changing the layer mode doesn't really help out.
Keep it up (:
