I like it. Good use of color hues to bring out the subject. Here the main contrast is due to sharpness of the anthers compared to the flower pedals. The small splash of green at lower right might be a debatable point - too small to add anything while upsetting the color scheme or a nice little accent. Like the rotational orientation. Cropping and DOF are just about right too, though I may have looked more closely at the in-focus pedal part at upper left. Great shot overall.
Cool shot..really like the light in this. Not too sure about the space on the left but that can be very subjective.
