Cool shot. If the camera is in the hole, did you jam the flag into the green next to the hole? The golf course people generally frown on that, but I guess if you fix your flag divot thats ok. I think it would have been better without a brand name being so prominent.
I really like the creative perspective here -- somehow better lighting (and i am not sure how you could do that -- maybe external flash?) would help the execution of this -- it seems like had to bump up the light and color sat in computer maybe, and that resulted in a halo effect around some elements.
Not enough detail, too blurry/fuzzy. Switch to macro view on your camera (should be a little illustration of a flower) to take detailed, close-up shots. Interesting concept, though.
