As for the sig, looks like a background, with two c4d's added on overlay. You should have added C4D's at the start, then smudged then about, to get the flow of the sig you wanted, then added the C4D's on overlay, and colour dodge, just to get a nicer background, with better detail. The face isn't too brightened, it brings the focal point to the render more. Text isn't the worst, can't really see it though. I don't think you will be able to add depth to this signature, unless you change the background, but for the depth you have blur parts of the background, use advanced lighting techniques etc.
