What I do love about this image is how the lily stands out so much from the dark background, yet there is just enough of the stem or leaf in the background which keeps it from looking like it was cut and past on. I do quite like the saturated look, but I would personally take it down just a bit as I think I might be seeing some 'over-saturated' areas where the colours almost glow (in the very middle as well as the upper left yellow petal)
Nice image though, great focus.
