I think this photograph is quite good without doing anything else.
The three elements that I use when evaluating images today are:
1)Composition
2) Lighting
3) Technical elements
4) Emotional appeal
In no particular order, the lighting and technical elements are IMO spot on. I think the lighting and time of day and setting is great combination of luck and skill. I'm thinking largely skill because your exposure in combination with processing retains both highlight and shadow detail.
Would I change anything? As for emotional appeal, a lot of that comes down to composition. Does they eye travel through the image with entry and exit points? Does it get stuck at any point? Are the elements balanced and how do the visual elements harmonize. This all comes down to taste and how one feels (psychographics). What I think and feel will most certainly be different than others. But this is what *I* think...
All of the elements are there for an outstanding image. One thing I learned in photo school is "eliminate as many horizontal and vertical lines as possible. Look for lead in/lead out lines. In this case I think re-cropping might be an option. But again it depends on taste and the message you're going for.
As I look at your original composition my eye gets stuck on the dirt patch on the lower left. It doesn't have as much interesting detail as much of the rest of the image. I think it had excellent potential for balance I felt it pulled the image out of balance a bit. Also the straight vertical plow lines were a bit static for my taste, but not objectionable. IMO a little more dynamics in the composition might be more interesting. Again, personal thought and not even an opinion at this time. More of a question than an answer.
I've taken the liberty of doing some a minor composition adjustments for comparison.
At the bottom is your original image. Moving up from there is "option 3", just changing the aspect ratio by cropping off the bottom. Everything else is as presented. The topmost image has some cropping and a bit of rotation to add a bit more interest and purpose of movement.
Please don't get me wrong. This is an excellent image to begin with. You asked what might be done to make it better so thought I would offer up some options, if for no other reason than discussion. Great job!
