It might have made an even more interesting effect if you had the camera focus on not only the top but the underside of the top of the mushroom as well. That way focus on the subject is less confusing. But that aside I like it.
It reminds me of an umbrella'd table for a café c:
Beautiful. But I think it would have been even better with the whole mushroom in focus. Not the focus in on the hat and the leaf in front of it by the bottom of the image. It steals some of the attention. But it's still very pretty.
