I love the atmosphere, despite it being not entirely correct. The angled rocket also struck me, but I would probably just tilt it a bit, you wouldn't see that really at its feet. More importantly, I would shift the camera a bit to the left, so you see more of the valley, rather than the 'dull' heights on the right, and lift it a bit so the second (dark) height isn't inline with other horizon lines, if you get my point.
