This is a very pretty composition. And I like how the neighbouring flowers set it off in the background. I do have one little suggestion if you don't mind. It's a touch over expsosed but you could easily adjust the contrast levels in a photo editing program and then it would be absolutely perfect.
Outstanding!!! Love the way the flowers stand out against that green background. That is a amazing shade of pink. Mother nature at times can really out do herself when it comes to colors. Great photo!!!
