Morning Glories, to me, are all about color, and texture and light. I like how they usually seem to be glowing from within. Don't know that I captured that well enough, but that is what I tried to convey.
Topaz adjust, duplicated layer, added 2nd layer of Topaz detail, brought back to about 12%, erased back to background in places, merged layers (multiply), dodged areas of blossom to emphasize light. Burned shadows to darken.
If you look at this from just the right distance it is a perfect and rich distillation of the heavenly blue morning glory experience. The heavenly blue blue is one of the most challenging blues.
