Ta-daa! The absolutely last edit:
Edited hands, butt (just a little), horizon (was 1 pixel unaligned, also moved it higher up), more shine on the apples, also dithered them all instead of just the two from before, made the frame a little thicker. Plus some other small nitpicks. I am really happy with the result, but I need to move on now. So this is definitely the last edit.
(Feel free to lock this topic now.)
