Rahul,
No idea why you are facing this image uploading issue. Will look into it.

In your image, I would crop a bit from the top to eliminate that single drop. This image needed a higher aperture to have enough depth of field to cover all the leaves in focus. Some sharpening would also help.

It is important to isolate and simplify compositions. Rain drops on one strand of leaves would be better than showing more leaves in the frame. The leaves at the right bottom of the frame don't add to the image. Keep on experimenting. Thanks for sharing.

Cheers,
