I have more decisions to make when I begin work on a picture book: Should I use pen and ink or paint? Should there be color? What colors? On the other hand, the decisions aren't as complex as the ones I make while digging into a character as I write a novel. Picture books are more 'bare bones.' I don't have to worry so much about description.
Whether or not you agree with Ayn Rand - and I have certain issues with some of her beliefs - the woman can tell a story. I mean, the novel as an art form is just in full florid bloom in 'Atlas Shrugged.' It's an unbelievable story. The characters are so compelling, and what she's saying is mind-expanding.
