Beautifully composed. Perhaps incorrectly, I think of calla lilies as being white, yet the one here shows up as a value of grey too near neutral. Higher exposure may just knock out the highlights, so raising the shadows in concert with raising highlights might just add that bit of brightness I think these photos need.
A gorgeous set of images. I agree with Terry that it is worth a lot of effort to bring the processing to perfection.
The first two are good, but the latter couple strike me much more (maybe because they are "less flower" and "more abstract" and therefore a better testimonial for the concepts of beauty and elegance).
