Compositing in Cinema 4D

Recently I have been experimenting with compositing 2D and 3D images in Cinema 4D. The way I've been doing this is by placing backgrounds into the project, and then adding the photo as a texture. After doing this, I add a camera and adjust the perspective to fit the photo. Once the camera is in position, I add cubes to the project and move the points of them to fit the geometry, while respecting the perspective of the photo. After adding the cubes and getting them in the right position, I add the the photo texture to the cubes, and change the projection to 'frontal'. This makes it so that the texture of the cubes matches the texture of the background. This creates an effect which allows the 2D image to have layers parts, so it can be used in 3D.

One test I have tried is using a New York skyline, and attempting to make the buildings 3D using cubes. I feel it worked well, if slightly strangely put together, and hopefully, now that I am considering using this technique, I can streamline the way I do this.

I added lighting to the project, to make the changes more notable, seen below. The buildings on the right have been composited, whereas the ones on the left have not, to show the difference between the two.

I may use this technique in my animation, however, since I am very inexperienced with the technique, I may simply opt to create a full 3D background in my animation.
