Beautiful. Nice to see smth little different. While a lot of us tried to take a pic of smth yellow you got the yellow background. Indeed original. Nice and crisp pic. Good execution. The composition has something I don't like. Might be the bottle that seems to be too long. And of course if wasn't that reflection there. Good try! Good luck!
It is really difficult to retain definition in highly glossy petals. I have a number of bright red flowers which seem nearly impossible to photograph in natural light so that I retain definition. Here though, you have brought forth highly saturated red, yellow, and blue in a very nice composition which relies to some degree on bright lighting. The question is can this be achieved under diffuse lighting? I really like the blue and yellow. A 9.
Maybe not original ;-) but it came out really nice and simple. It would look even better if you cloned out that glare on the bottle after the challenge. Very good shot!
