Two main things struck out to me on this one, first, love the reflection effect you used for the blue lights on the render's face. Well done and it does not look out of place. secondly, that its c4d'd to hell and back. That being said, its not a completely abuse, you can still see most of the render, and it almost looks like she is walking through the darkness. overall I say about 7.5/10 if some c4d were removed, and perhaps some smokiness added to complete the scene it could easily be a 9.
