It is a little difficult for me to pick out what about this shot leaves me a little unsatisfied. Color is great, execution and lighting, ditto.
What I am missing here are the cues I normally get, where to stop looking so that I am focusing on the most important center. The very first 'seed' (?) is in fine focus, the next one is virtually the same size but in slightly less focus, and so on. My eyes go back and forth, not knowing what is the center. From the first to the third, because that has the same color and pleasing angles. The second is turned away, its point hidden.
The placement of the most in-focus 'seed' where the eye enters the picture is disconcerting and, I think, ultimately is the unsatisfying element.
