Macro shots can often be very interesting. I like the motive you've got here but the composition IMO could be slightly better with the drop placed further from the central of the image, maybe a little bit more down to the right corner just the drop's size down to the right. And then I think it's better to crop one third off from the top. Then you would have a better composition IMHO and a better photo. The green overall tone is great.
I like the composition, colors and focus best. Except that there's a leaf in the picture the tie in of the subject (water droplet) to the theme isn't as strong as some other images.
Beautifuk composition. I do like droplets on leaves shots but sometimes they can be a bit samey. I love how this one is more abstract and is all about that double waved edge of leaf and the almost perfect sphere of the droplet. That's just beautiful to me and composition very strong.
