Okay, I'll be honest. I don't like this one :/

The only good part is the architecture and some of the textures, but the rest is pretty bad. The biggest issue here - highlights. They blend in with the environment, the color doesn't stand out. I can't tell where or what is the light source. There's no difference between the light source or the highlight. And worst of all, most of the highlights are just basic lines who don't bring any additonal texturing to the scene.

Alas, better luck tomorrow.

@Neoberylium I think it'd work as a great sketch, you've created an interesting space: The perspective and low point of view are cool, the multiple corridors suggest different paths and places to go, architecture out of frame that I'd like to explore. And all the surfaces are full of topography, which is also nice. There's a scene and an atmosphere there. That's the difficult part and you got it right.
I would leave the structure, think about where the lights should be and repaint from scratch
@Neoberylium or not, I'm not the boss of you, but I see a lot of potential for an Aliens inspired setting if you place the light sources thoughtfully and play with lights and shadows. All that topography is an ideal playground for projected shadows.
@enriquericos
oh wow, I think you just described it perfectly! I was thinking of maybe redoing it while keeping the structure the same, but I had no idea how I wanted it to look. But that aliens inspired setting sounds like the perfect thing
@Neoberylium You were almost there, but I'm glad I could help!
