It's ok to make dark backgrounds, but the first one is definitely TOO dark. You can barely see anything in there. At least for me, it took some time to notice the ground and walls. Here, the word "highlighting" would fit better instead of "shading" :P

For the others: I see that you've become addicted to the Clouds-filter, eh? I for my part usually like to draw them or, when I'm not in the right mood, use a cloud photograph and "littlefighterize" it :P
It just doesn't look too realistic if you use the clouds filter like that
