I'm kind of surprised the bloody things (bales) aren't rolling downhill to the left - it looks as if they've been caught in frozen motion.
I enjoy the warm, raking light, though. But I've long been puzzled about why big round bales are such a popular subject amongst amateur and stock photographers. Yes, I know, they have a form, but then so does mostly everything else. Maybe if you were doing a documentary about agribusiness, or shooting for Farmer's Weekly ...?
Interesting sky (different cloud-types at different heights). The best bit.

That last jpg looks much paler and less contrasty by comparison - is it from raw without user-adjustments? And we can see your sensor smudges. Personally I'd have been inclined to keep the mid-tone about where it is but up the contrast, as a sort of base-line ...
