Excellent composition, Gigi. The combination of the paleness of the blooms and the backlighting produces an interesting effect-almost like the blooms are transparent. The background is perfect for this subject.
The faint yellow background goes very well with the blue flowers. Great detail showing all the lines in the flowers. A very pleasant arrangement. Simply beautiful.
Your processing is flawless and makes the petals look like they are so delicate that if touched they would break apart into a million pieces. No nits here.
