Especially given your title for the image, I think the image could have been improved by pumping up the contrast so that your white areas are much brighter instead of a murky gray.
The pale horse certainly becomes the predominant subject, but there's a lot of other distractions in the frame. I do like the composition's implied ascending line from lower left to upper right.
Impressive tones and dramatic clouds save you here. I don't even mind the power lines, although some might say they distract and give away the less-than-timeless nature of the picture.
