I must confess to a bit of ignorance here because usually when the question of whether or not something works, it is in comparison to something else, so my question back to you is Does the crop work in comparison to what? - another crop? - no crop? - square versus rectangular crop? - etc. Why is the crop unusual, again in comparison to what? Perhaps some additional information might be useful.

LOL You got me there !

Since this was an unusual crop and did not adhere to any crop ratio, hence the Q popped. I guess I have my answer now.
Rgds,
So my next question is -
Who says you have to crop to a "ratio"? I suspect a lot of us do for one reason or another, but, if the crop works for you, then that is all that matters.
For me, this is a nice picture, regardless of how it has been cropped. I think that:
1. there is just enough sky to tell the viewer what the weather was like and it provides a nice balance to all the green in the rest of the image. I would not crop it out.
2. the people in the lower left thirds position (more or less and talk about "rules") provide a nice sense of scale and they balance off the building in the upper part of the image.
3. there is a lot of "green" in the image, but it is not overwhelming.
4. there are converging lines in the image that take the viewers eye towards the top part of the image.
Anyway, I could probably go on, but you get the idea. The goal in photography (photographic art) should be to present to the world a picture that has some emotion and tells a story. For me, there is some emotion generated by the mere size of the "fields", which is why the people are good to have for scale. It tells the story of people "administering" (what ever that implies) their paddy fields. In my mind, this is a successful image.
I always try to ask myself - "Why would anyone be interested in this photo and what elements can be included or excluded to make it truly great?" - I am not always successful, nor do I always remember to ask myself that question, sometimes I am just experimenting and no one will ever see the result, but I always try to remember the words of Ansel Adams -
You don't take a photograph, you make it. - For me, my goal is to produce "art" and what I do to the image and how I present it, is my choice and no one else's. What counts, for me, is whether or not I like the result and if others like it, then that is a bonus. Some folks might think that perspective is a little conceited, so be it. Do you think any of the great masters really cared what others thought about their work - I doubt it very much. Anyway, enough personal philosophy for now. You can agree, or disagree - your choice.

P.S. Now that we have beaten this one to death

, it would be nice to see the original image.
