Anna.....
Just looking at this again and reading your comment....
I can understand why you would think some reflection are missing, but I can back up what Lee said as I know they are not.
This was the park I lived next to when I lived in England, I actually have one of my own shots taken from the very same spot as my desktop image.
What you can't see in Lee's image is that the trees you think are missing are in actual fact set back a very long way from the water, that is why they don't show in the reflections. :-)
