First off, what really drew my attention to this photo was the colors. The contrast between the warm yellow and orange of the flower and the cool surrounding blues is wonderful, and the combination of the two colors in the droplets is simply amazing.
I really like how you have the camera so focused on the center droplet and the petal it's on, the blurring of all the surrounding elements gives it a really dreamy effect. I find the far right side of the photo to be a bit distracting, however. There's the spot of bright red in the top right corner that just doesn't seem to fit with the rest of the photo, and in the bottom right corner is a similarly out-of-place pink spot.
All in all though, this is a wonderful photo, and it's easy to see why it's been faved over three hundred times.
