All great. Hard decision. I like the dragonfly because I don't have the opportunity to photograph them....and the colors are beautiful. But you chose the right one, it looks like the flower is glowing.
Oh I can see why you had a difficult time with this decision as they are all quite good. This one is a bit unique though and so I think you ultimately made a good choice. You don't see this crop with this flower and I think the way you've done it really adds some appeal. But as I said -- any of them would have made excellent pads as they are all great shots.
