Love them all. I recommend the next time you have a chance shoot these lovely flowers you use a larger aperture to blur the background. In #3 you have done a wonderful job composing and capturing the flowers but, personally, I find the background too distinct and a distraction. A nice way to do this is to increase your focal length (short telephoto) which will compress the image and then stop down say to 2.8 or lower depending on the lens. The flowers will be sharp the BG a blur.
