Well... That's a different take on love.
Red roses might say love, but this is a bit of a stretch for me.
I like the angle of the flower, and the close-up. It might work as a square crop. Something about the horizontal orientation just doesn't seem right to me. I don't really think you needed water drops in this one. They don't add much IMO, and the light reflections on them look a little like hot pixels. The focus is good except for that one leaf - maybe it you turned the flower some so that it isn't coming forward so much. It wouldn't really bother me if there were other parts that were out of focus but having just that one area blurred sort of makes it pop out too much. I like the lighting on top and the shadow on the petals from the leaf. I'd like a little more light on the bottom and stem though because there just isn't enough detail/contrast there. The area in the middle of the petals - between the bright spot and the darker areas - is the best because you can see all of the detail.
It's really a cool shot though maybe not the best for this challenge. High quality with just a few nit-picky technical quirks. It's probably can't appreciate a lack of color at all.
Challenge met, I guess, although I've seen stronger associations ... w/out the title I wouldn't necessarily think of love. I like unusual flower shots and b&w is unusual, so points for creativity. I like that some of the texture of the rose petals is visible. The stem and leaves look very pale, I would expect them to be darker but maybe you just used a dark rose. That does give this photo a little unreal feeling though. Your lighting is uneven, even if there aren't any glaring hotspots. I'd love to see a little more on the bottom of the rose and the stem, too.
if I could vote, I would give you a 10 (best photo yet) however, I think the masses might like more of a pure black background... looks almost like fog...
