This would have been perfect if not for the extra reflections in the color marble (I know a bit nit picky here). I give high you high marks but could have gone a bit higher. A lot of time and effort went into this composition, it is a beautiful shot. I may have had someone/something hold up a sheet behind me to remove the window glare on the left and the fridge looking thingy on the right. The red spot on the marble seems out of place but on the none color marbles fits the picture perfectly. Just my thoughts.
Not sure that selective desat really brings anything to this picture. It looks more like a gimmick here. High levels of noise and nothing is particularly sharp. Composition seems a tad tilted.
