Nice focus on the nearest parts of the lily but the shadows on the petals are too pronounced, I think, and the farther petals and especially grain of the wood lack definition.
Love this shot, the B&W processing is great, at first I was wondering about different DOF but in the spirit of Ansel I think you are on the right track here. I gave it very high marks, good luck in the challenge.
Excellent conversion to b&w. You nailed the focus and detail on the flower. That said, the wood grain is OOF. The lack of deep DOF creates a distraction. I admire the control of exposure, especially on the flower which has superb detail in the shadows and no blown out highlights.
