in order for this shot to really work well, the rest of those flowers really need to be blurred out of focus to pull the eye right to that middle flower. You definitely have a potentially great photo here and it is certainly worth reshooting if not just for yourself.
Nice. I like the colours and the composition. There's a variety in the image thanks to the arrangement of flowers without compromising the theme... clever. Contrast is great, as is the focus... my only issue with this is the petals at the bottom sticking up and out of the field of focus. Other than that, love this photo. Well done.
