black and white flowers aren't normally that interesting (to me anyway), however, your picture is great. i really like the tad bit of grain and the overall soft feel.
This is one of the loveliest flower shots I have seen on the sight. The soft focus and lack of color give it an elegant feel. The lighting brings out texture of the petals and adds a nice depth to the center. If I could vote, you'd have a 10 from me.
Composition: Nice position of subject. Good choice of image size too.
Technical: Excellent contrast and brightness, but the noisiness is fairly obvious, letting the overall image down.
Meets challenge: Yes
Overall impression: Minus noise, good pic.
