One of the blogs I read regularly is Oswald Iten’s, Colorful Animated Expressions. He’s recently done a couple studies on background and lighting for the Tom and Jerry Short, The Milky Waif (Here and here).
If you’re not already following his blog, I think you should. A quick scroll through his past posts will reveal a lot of very well written and intelligent posts pertaining to film making and animation. It should be right up your alley. 🙂
