Wow. That's really close. My first reaction to the shot was 'ew'. It looks like we are looking up a nose and there are seeds jammed into the nose. lol So, that's my first impression.
Focus looks really good and texture in this shot is amazing. I like the wet texture on the white part of the apple and the seeds are a dark smooth. That makes for a nice contrast in textures.
Lighting seems a bit dark in the center, with some bright reflections on the white of the apple.
I wonder how this would look at a different angle. Maybe not so centered in the photo. I think one comment said to off center it a bit, my suggestion would be to try to just make it so we are looking at it from a more of a side angle rather than straight on. The seeds could still be in the center of the photo, but we would not be looking dead on that way.
Overall, you have a nice pic of a good looking apple.
