Again, I can't think of too much to complain about here. Another beautiful job.
If I had to complain about anything...as before, I'd lop off a bit of the dead space at the bottom of the photo..maybe the bottom 1/8th or so. I think this composition lends itself to a wide landscape panorama format and I don't think it hurts that the spiral is dead center horizontally.
The green under the stem and dark space over the stem reminds me of a "yin-yang"
It's beautiful how the stem gently arcs in the background, then changes inflection to end in that tight spiral.
You've also got a very interesting sense of movement in an apparently static shot. The spiral still has the leaves held tightly near the stem, and as the stem fades into the background they gently unfold. I can see the time-lapse movie of this plant unwinding in my mind!
The more I look at it, the more I love it. Definitely one of your best shots! Thanks for making my Wednesday!
