Underground Colony

I'm trying to make some sci-fi scenes with my recent 3d models which I've created without any direction.
I'm feeling brainless at the moment,nothing is coming out. It's really tough to come up with new idea in every time.
I started this work with different idea but it turns into another thing.It's really nice to see that sometime we think something but the result says different. Sometime we satisfy, sometime not. Anyway I'm happy with this outcome.
Hope you like it too !

^{Edit: just change the light color. The previous version looks a bit unrealistic to me.}
