It is too small (no, I'm not complaining, just realizing that DPC format is not conducive to panoramic photos - you are using max width here). For this reason, I would avoid submitting panoramas to DPC challenges.
It seems as if the bottom and the right side are cut off - that the canvas is a pixel or two bigger than it should be.
Otherwise, in my opinion of course, there should either be more of the sky shown in the photo, or no sky at all. This way it looks artificially cut off. The field itself is lacking contrast in the details.
the colors and composition of this are very nice, but it's not being sharp really detracts. It looks like a cheap consumer camera, though at this size (640) you should be able to get a higher quality out of it. 7
Lacks dof. No real focal point at all. Bit light. Love the almost panoramic view. But then I am biased living in nature. Perhaps a touch of color balance or hue adjustment to enhance the gold/yellow of the hay (Sorry hey).
