This has beautiful, vibrant colors and the DOF is awesome. A couple suggestions,
I think the inside white border would look better yellow, and A quick run through NeatImage would get rid of the minimal noise I am seeing. Great job!
Very beautiful. It looks like the contrast and saturation is boosted a little too much because it is slightly blowing out the yellow. The cropping is very good.
Love the golden tones and the lighting is very good and contrasty. This shot is more artistic than scientific representation and as such I don't believe it meets the challenge them 100%. Compositionally too centered and the two "bunny rabbit ears" shapes in the lower right compete for attention.
Gorgeous. I love everything about it. Obviously the strongest feature is the lighting and razor sharp focus on the subject. Centered comp seems to work due to negative space in the background. Hope it does well inthe scoring.
Lovely use of colour and light to create an almost abstract imag and yet one with recognisable subject too. Purple hue o stem is a touch too strange but otherwise love it.
I love the blue and the pattern in the water drop! I like the subtle and abstract forms of the tout of focus flowers as a back drop, but I crop in more from the top and the left - removing the bright bits of the stems that distract the eye. Beautiful shot!
