The thing is, you have to decide what you want your picture to show. If, for example, you wanted to show the flower in full bloom juxtaposed with the ripe one on the left, then both should have been in focus, or at least the one on the right somewhat more in focus than you had it. If, on the other hand, you were highlighting the seeds holding on to the base, then the background flower on the right does not contribute, and should, in my opinion, been out of the image frame completely. Either interpretation would work, but you kinda parked it in between. I'm a big fan of keeping it simple - select your main subject (or theme), and arrange all the other elements to support the main subject, or minimize/get rid of them.
Looking at the image, you have a potential symmetry play: shoot the dandelion head with half of the seeds on (say, on the left), and none on the other side, with the image centered (to tell the viewers - us - that we are SUPPOSED to see symmetry), and the background out of focus (because the context of where you found the dandelion is not part of the story).
