It kinda bugs me how everything is blue, and then his wristband + headband are red.
Also, it might flow, and have depth, but it doesn't blend. He's just, there.

Still, it's a great piece.
7/10

If you stood in a blue room,
would that make you blue?
Partly..depending on the lighting I suppose.
(not counting blacklight)
I did add some blue to the render.
Only for shading where I felt it was needed.

Try using adjustment layers.

lul wut...you can't tell I used them.?

There's about..6 g-maps.
Curves.
Cooling filter
+2 Vibrance.
+1 saturation.
Exposure
Contrast

I didn't just paste c4d's.
Every one of them were manipulated somehow.
Whether color, or adding stuff to them for lighting..
so not really sure what you mean.

Edit:Good c&c Doc..Pretty much spot on with what was originally bugging me about this.
Because I don't really consider this a great sig, I didn't bother saving .psd.
So, I guess this is a done deal..but I'll keep what you said in mind for next time around.
