Thanks for posting the full image. It confirms what crossed my mind: the focus is fine. However, unless I'm mistaken, the feeding post moves on the two metal hooks, and I believe that it moves very freely. I think any lack of sharpness is subject motion, honestly.
I do think it's a great pic. Again, thanks for posting.
