First, I am jealous of you having a ranch in Wyoming! What a great thing.

On to the shot...sloped landscapes are tough because people obviously like a straight horizon unless it is a mountain. In my photo club one judge downgraded a desert shot only to be told that was actually the landscape slope..but it was an awkward shot in any event. Darned difficult to make those shots look normal.

You have two competing exposure needs...the sky and the foreground. I think the sky is most beautiful...What a great day!

The foreground is heavily shadowed and your subject, the mower, is partially obscured by grass and by dark shadows. Thus, the viewer does not see the mower as the subject of the shot...it almost looks like an artifact that may or may not need removal.

Please do, I would be very interested in what could improve this shot as well as my learning curve.

I downloaded and messed around wit this shot in LR. Upped the exposure and reduced the shadows in the foreground. The shot looks better, but still, the mower is not really recognizable as a mower...there is also a fence post sticking up in the middle of the shot which needs to be removed (IMO). I also warmed the foreground a bit. I also played with darkening the edges to force the viewer to see the mower.

So, I see this image as a great memory of the sunset and of your ranch. I also see it as something that I would do more post in and display at the ranch.

With your permission, I can upload my interpretation of your shot...
