that would work better with a more readily recognizable object. in my opinion, when you're including a secondary object in your photo to scale it, it should be more clear that it's intentional. i'll take your word for it, but in this case it doesn't really look like it was. :?
I like the pano-crop. I'd like to see it with just the bottom cropped off, leaving all the sky, just to compare.
This is the sort of subject matter that seems to have it's own built in sense of scale, and the desert shrubbery adds the sense of depth. I found the fence post distracting; like a Budweiser bottle lying there. But maybe that is part of the message in the photo. Sometimes I get fed up with litter or power lines and integrate it into my landscapes. If you can't beat 'em, join 'em.
