This shot is interesting... There is a synergy throughout. The sunlit cotton at the bottom provides a good balance to the towering clouds at the top. The mountains and clouds provide subtle leading lines to the sunset, ensuring that no matter where your eyes begin in the frame they find their way to the main subject. Which is absolutely crucial, landscapes as sweeping as this often have issues with an obvious subject.
As far as criticism; One issue I have, though not a large one, is framing. The horizon is a bit too centered for my tastes. There are a few issues with the foreground as well; the plant that stands the tallest in the left side is distracting and unnecessary. A slight move to the right to get that out of the frame would have been great.
Overall; good work. You did quite well with the exposures here and I applaud you.
The first thing I thought is I actually haven't seen many photos of cotton fields, maybe none have caught my attention but this is the only one that's really stood out to me.
I like the way the cotton lights up while the rest of it stays for the most part dark, it makes it really stand out quite nicely.
Also I like the sky, it gives a more dramatic effect than if it had no clouds, and the way the sun colors the sky is quite wonderful as well. One thing I notice about the sky is the left corner is a lot brighter, I know that's just the way it is but it looks a bit odd to me personally. Maybe if you had moved to the right just a touch it would've balanced the sky colors.
I like how you framed the sun off to the side though rather than in the middle, it looks quite nice. I do think maybe a square crop could work for this as well?
Over all quite a nice photo (=
