Here's another breakdown on several shots I worked on for our short film EL Camino, from the beginning this was a DIY filmmaking style, so we had to solve a lot of these shots ourselves, here's my process on some CG backgrounds for both full CG and live action shots.
Thanks to all the amazing artist that helped out!
