Mmmm, fantastic. Nice lighting - though I'd maybe have been tempted to use a blue or green background instead of black. I'm not sure what that would do with reflections though. Nice capture - I'm envious of all these high-ranked photos you seem to be making!
There is another picture like this in this challange and i love them both. The balance of positive space and negative space is bery beneficial to the picture, but the reflection of the droplets near the stem of the apple make the dropletts look like they are something other than water.
Not voting just commenting. Lighting is ok, dof is a little too shallow in my opinion (is the stem really the important part of the subject?). Not a lot to get engaged in here.
