Where to begin?

First of all, I adore the texturing on this. Then there's all the little light reflections (so much shine!). And, of course, the thematic contrast between a memento mori's usual themes and the worm, which becomes less of a contrast and more of a complement the more you think about it. I like the diamond composition and the contrast between the worm's head and the blank wall. Finally, I need to give you props for the attention to detail on the apples - not just the skin striations, but the little sugar spots are even included; did you work from a reference, I feel like I could almost guess the variety. Maybe fuji or honeycrisp.
