I'm not an expert Critique writer, but i will try.
Woah, you've really captured this photo so well. The softness of the surrounding leaves and then the intensity of the water drop, perched so bluntly - yet tenderly on the leaf. It makes the photo look naturally beautiful.
I love the way the drop shows a detailed reflection and image of what you can't really see in the blur of the background. Definitely, a piece of nature captured in a tiny drop and it's an amazing shot.
From this photo, you get a sense of freshness and calmness given off by the leaves with the green and yellow mixing and blending so well as well as the drop looking and being so untouched. It was a creative idea and you've turned it into a great piece of art
Great work, i love it.
