Nice depth. I personally find the sig to be cluttered but I'm supposing most of that is from the render. That area around the text needs to go I would create more flow to distract me from the clutter On another look I am focusing more on the gold jewelry earring more than the face. Is this intended?
The depth is nice. i also like the colors but like rathger already mentioned, it looks cluttered. erase some parts of th render
