It is a beautiful bud and photographed very well. I like the background, it adds emphasis to the tulip.It looks as though it is reaching up to the sun.
I would have preferred the flower to be a bit off- centre, but take no notice of me , I know nothing lol
I like the way you varigated the background, from dark to lighter. I thnk that's very nicely done..I love that single tulip, so regal...nice colours too. Verena
