there needs to be more effects. Right now it looks like a wireframe and some brushes for the light source. use the burn/dodge tool to create shadows and highlights
About the brushes: There were no brushes used.
The light effects is Rendering -> Sun.
The effect on the left are smudged C4D's.
Because this signature has a big render and small place to work with I left out more effects.
In the first one there were some C4D's and effect layers but it totally messed it up..
I don't like the soft brush, or lens flare or whatever you used right below her. Too much white all over, needs more solid effects to give it some depth and atmosphere.
Have you honestly posted in every single old thread you could find with spam? I'm seriously considering forumbanning you.
EDIT: Just requested it, good riddance.
