First off, I love this photograph. I've definitely seen a lot of pictures here on DA of water droplets, especially on leaves and petals, but this is one of the better ones that I've stumbled upon.
I really like the focus in this piece. You've perfectly captured the water droplet and I really like the tiny white glare you get in the droplet. Also, having the warm yellow in the center really compliments the red underneath it. It's really nice that coming off of the droplet everything gently begins to blur and becomes almost abstract. It just leaves me with warm, fuzzy, summery feelings.
As for the little stars, I love your vision here and think that your technique is very well done, which allows this piece to have a lot of impact. I did take off a couple of stars just because I've seen a lot of these kind of shots with water droplets, but like I said, this is one of the better ones!
Beautiful colors and shallow depth of field. The only thing I would suggest is having the water droptlet just a tad bit more in focus (Something for next time, right?) Other than that, this photograph is lovely!
