A great moment with wonderful atmosphere. Despite the title, though, I wonder if the brightness of the sky detracts from the mystery of the scene and suggest cropping "the top" off. To this end, I've attached a slightly re-worked version that also bumps the contrast and clarity to emphasize the drama of the moment. My students find this to a healthy exercise in learning to see differently, so I hope I've not offended you in doing so. If so, I will remove it from the post.
