You got a really good splash and shape to the crown. However, the focus totally missed the crown. I think a little tighter aperture would have helped you bring the whole scene into focus. I would have liked to see a whiter surrounding to make the purple stand out more. The creamy or grey color is not very complimentary to the purple.
I have always wanted to try this, but never got around to it. The reflection is very cool, but for the photograph to be truly successful, I feel it needs to be sharper.
