CG Car Model on Backplate in 3ds Max

I was given the CG car models, but I textured and placed the models on the backplate I was given.

Final Comp of the CG car models on the backplate

This is my first texturing pass of the cars after first placing them onto the backplate, and reflecting the HDR image into the environment.

First pass of matching the CG ground plane to the backplate, and testing how the HDRI will reflect into the scene.
