I was traveling through a small village on the outskirts of Bangalore, and happend to see the brother sister duo, and could not resist capturing the moment! The elder sister seemed to be so protective and caring, oblivious about the world around!
The scan quality of the picture wasn't great, and adding to that, I cropped the image which probably reduced the clarity further! The orignial slide looks better!
I like the composition, the colors and the subject, but I think you sharpened this photo too much, or enlarged it too much, causing unsharpness and that's a pity. Nice capture though.
