Cute. Well exposed, I think. The lighting on the bottom of the book works well to emphasize its texture, as well as that of the grass. You could easily have ended up with a blown out or completely white sky, but it looks pretty good.
A polarizer would have done a good job on the sky, if you've got one. Nice choice of focus. I usually don't like oof foregrounds, but it works at this scale.
he he ... I was thinking of doing something similar. Nicely done. Good job on the focussing too. I would have moved/ripped out some of the grass on the left so that they didn't get in the way of the shoe, and showed a little bit more sky. Just my opinion tho'
