Anita, Beautiful light and reflection-Can you post any of your specs? Could probably take some off the top-it's a lovely composition and I like the infared B&W with this.
I agree that a crop off the top would also work. I think your focus should be on the flower and the reflection and the lily pads at the top don't really add to that so the crop would work.
Lovely conversion...I'm guessing a black and white conversion with a mask to let a little of the color back in?
Another old foto. My first test of the original Canon 5D to see how it would handle the whites. I converted in Color Efex pro with infrared filter. Played with values. The trick is to bring it up in PS again then reduce the opacity a bit until you get the feeling you like.
