Look great for mountains! The blackness of the sky and the greyness of the rock, though, makes it kinda feel like we're looking at a Lunar landscape though...we could easily be pointed to the clouds to indicate, hey, it's not the moon, we got an atmosphere to work with. But even for a night shot, I think it would still retain SOME color beneath the moon-light.

I really like the geometry of the backing mountains, and how the light source helps us out with the mountain range's shape.

Keep it up! Push yourself, and let's see what ya got!
