Working on the new chapter and before I do a detailed render, I test out the scene first with a rough one (notice it's quite noisy and low resolution).
After everything is properly rendered, I'll do drawing in the details. It's a bit funny how it used to be that drawing takes the longest time, but now with 3D, it's making the models and setting up the scene that takes the longest. The drawing part now is one of the shorter processes.
