Glow

Isn't it frustrating when things don't turn out the way you thought it would be? Lighting and rendering really pisses me off. I wanted it to look like the night scene from "Theme Planet" by Michael Sormann:

Instead I get this:

BLUE GLOW! Somehow the texture glow has become blue. Though it still kinda looks cool, somewhat like underwater city. Then I managed to fix it by placing ambient light among them, and here's the result:

Doesn't look bad, but It sucks compared to Michael Sormann's scene. I need more practice, but I suspect many post processing steps were taken to produce the exact result, and I've completely clueless as how to achieve that. If someone could shed some light it'd nice.
