I like that bit of sparkle you have on that bead of water. It appears (on my monitor) that you back ground is not completely black, I can only notice because it looks like you used a black brush to remove something. It would not have been to hard to mask and replace the background with black.
The editing in this makes it look like a painting and I like it. It is bright and colorful but not overdone and the lighting is just perfect. Very nice for sure!
Wonderful shot! Just love the starburst on the drop. If you get a chance to reshoot this, try it with a black cloth as a backdrop, as your background is still visible here and a little distracting.
