As Meta said, the C4D's are put in random places just to fill the space, when using a C4D you have to make sure it follows the flow of the render.
The render isn't blended too much, so it looks like you added the render on a background.
Keep trying, using C4D's is not that easy.
Also, mo, you got a heck load of signatures, try to remove some.
