In this CAM there is not a lot of objects and it's HD, as you can see this is a CAM which take me a lot of time to work to make it perfect and not just 5 mins to copy paste from a render.
So, johnny, this is a cool CAM, not a lot of elements but effective.
I think you have to review your vision of a cool CAM.
Sure yours are nice but just copy/paste and I don't think you've a schema of your level with all the CAMs you have to make and where you have to place objects.
Remember it :
Be organized !
EDIT : Oh yes and STOP USING MY BACKGROUNDS TO CREATE YOUR CAMS, this background is my creation so make an other with an other background !
