Very cool! I would drop the stray thingy in near the center of the bloom. I like the lightness in the lower RH corner just to give a little variation around the perimeter. You might lighten up the center of the flower a touch for more detail.
Overall, interesting, artsy, and a nice conversion to BW.
lovely shot. the stuff in the background of the upper left hand part of the shot distracts me a bit but overall without really studying it my first impression was that it was extremely beautiful. nice work.
Nice b/w - good contrast level and gray scale. The center of the flower looks a bit too dark though and lacks detail. The foremost part of the flower with the DOF is fine, except the bent piece that distracts me a bit.
Very different. I like it. I get tired of regular, run-of-the-mill pics of flowers.
Maybe just 2 tiny little nit picks: the one strand is bent in the lower left quadrant and the white piece of something coming out of the center of the flower.
I like flowers and especially black and white and toned ones. Great composition and nice tonality. I would see if you can bring just a touch more detail in the center, just a little bit.
