HOW IT'S DONE: Re-creating Digital B/Gs

I frequently get questions about how I actually recreate these backgrounds. Today I was working on refining a B/G for one of my Mary Poppins Penguin cels, and I thought I'd show the process, step by step. There were actually eleven layers. Here I am sharing the major steps only. On rare occasions, a background will appear for a frame or two by itself, before a character enters or leaves a scene.
