I love the idea, gives a great sense of distance and perspective, that beautiful cyan sky totally lifts the image. I think the high and narrow crop works with the images lines but I'd have less of the black at the bottom as it doesn't seem to add anything to the image, you need some of it for reference but not so much I think. You've created a kind of abstract from reality here and I like it. Keep seeing things like this, it will make all your photographs more and more YOURS. I think I'll make a wallpaper out of this one. :)
