The following group of photos make up the layers for the background plate and ground related shadows. Since I forgot to shade the entire background plate during the shoot, you will see where I attempted to create one in Photoshop. In the final render you can see the double shadows. I was able to improve the shadows but not well enough.
Below are the textures that I used on the model of the ball. Thanks to artist 3V3R from CG Trader.
