The image was rejected with a comment - "there is no aesthetic and commercial appeal."

I get your idea and it surely looks interesting. In the posted image the ground seems to be a bit too dark and there are some fractals. This might be due to a compression in this forum (or is this linked to the original source?).

A question mark would be awesome - maybe you run it through PhotoShop and remove a small line of the tractor track? Additionally, it would be great if you could emphasise the tractor trails.

If the image resolution is high enough you might also try to put the tractor in the right third - this way a creative guy can post his text on the left and the question mark can doubt the message. The viewer can then also have the illusion that the tractor marks are very special and not a common pattern he has done multiple times on the same field.

Best regards,
