I'm most fond of 2C. I like the background with the pages blowing, but the filter on the art makes it look a bit ghost-like. To me, that emphasizes the connection with the sort of storybook world that Victoria looks like she's going to find herself in. So, overall, like that composition the best. I know you're going to be choosing a different photograph, ultimately, so I hope that you'll choose one that's got a bit more movement, is a bit more dynamic.
Looking forward to seeing the finished product!
