Cool. You should have cropped to exclude the black spots. I know you would lose some of the great white pedals but it would be well worth it. Or, you could have cloned the white part out a little as needed to save as much white as possible.
I really love this shot. Seems a little bit soft and maybe underlit, but I'm not sure how to fix that without overexposing the white petals. Regardless, beautiful photo.
