This shot really looks good - the colors are special for me as they tend to blend, and I like the fact that these flowers have seen a day or two, so their petals are not new and perfect.
You ask for critique, but I hate to try to impose my vision on yours. You, no doubt took the photograph you wanted. Or you might be wanting an opinion on a look you're not sure of, I don't know. The upshot is that this photo stands as is. It makes a statement - to me, something about age and resignation to imperfection (but these days, most things say that to me.

)
Having said all that, if I had shot it, I might have used a reflector, held down low, to reflect some light on the undersides of the flowers. Not a lot, so the shadows would still be there, just enough to show more detail.
