The horizon is too centered for my taste and the color of the ground isn't in good harmony with the sky. I really like the sky, it's very powerful, maybe the darkest part of it could be lighter and maybe the image would be better with more harmony between the color of the ground and the sky. Not bad.
I like the leading lines in this shot. It could have almost been used for the minimal challenge in fact as the road draws your eyes to the vehicle in the distance.
