It is looking pretty good. I would suggest looking into using depth of field on some of the renders. I am not familiar with cinema 4d but there should be a setting on the camera to adjust the focal point manually or even to target a specific object.(I use blender but it should be available on most 3d programs) If you are not familiar with the term DoF, it basically controls what is in focus and what would be blurry based on the distance from the camera. This can really make your renders look more professional and doesn't take long to adjust.
Keep it up, hope to see more from you in the future
Okay thanks! I dI that on my pictures but I must have forgeten on some of them because I did notice that and thanks for the tip! I agree it does make a great difference it's just a simple thing to forget when adding the textures. Thanks!
