What a great picture for this challenge - it looks like you can see forever! The green looks very yellow on my monitor, probably because of the time of day you took the shot. It might have helped just to desaturate the yellow a bit.
You chose a good subject for this challenge. The rows show the DOF extending into the background. It would have been great if they went even further. The hills in the background seem to be obscured a bit by haze. A polarizing filter may have improved the shot.
The crops appear extremely contrasty. There seems to be very little in the way of middle values. For this shot to work for me I would have had to seen the diagonals of the crop rows repeated throughout the frame.
this was a very tough exposure. technically impossible, I expect. But a very good try, and a great photo. just don't know if the exposure and saturation levels are enough for a top spot.
