In terms of lighting and vignette these pictures excell, the composition really brings out the focus and evokes a logical theme, each part complimenting the other. In terms of technique the eyes work especially well, the apple is alright with the lighting on it (in the second image mainly), but could use a little more of a wide gradient, as it stands it works from a distance but close-up lacks some of the sheen an apple should have. The colour edits and enhancement are flawless, and focally you really draw attention to what you want without much trouble, the photo is excellently done and the colour range is pretty well perfect.
I really like the photos overall. Great work.
