Hopefully you'll allow me to substitute the Indian Ocean for your requirement of a lake.
The image works for me because:
--the white flowers provide foreground interest and the shape of their collection leads the eye (almost points) to the middle and upper areas of the frame
--there are many layers (foreground, line of rocks, ocean, mountains, sky) that complement rather than compete with each other
--the clouds cast shadows that make the light more interesting than would be the case when shooting in between the ideal daylight hours. (I waited for the best areas to be brightly lit and for the best areas to be in shade. I didn't have the luxury of being able to shoot at sunrise.)
