It’s interesting how just a small addition can make something so much better.

I’d appreciate feedback!
I spent 3 days on this room; mainly because I had to think
what would be interesting to put inside and how to make it aesthetically pleasing.
(this is my 4th creation after scrapping 3 failed ones)
I’m not a builder myself, but to me, that looks like 2010ish style building.
I can’t build, so I can’t give any feedback 
Yeah, that’s about the same as I can give.
Aesthetic doesn’t quite match modern Roblox building.
I need to know what gives it the 2010 vibe.
If I can, I’m going to scrap this room.
I’ll remake this single unimportant room as many times as humanly possible.
That’s a great mindset to have! I think the main cause of the vibe is the lack of materials and lighting. Those things alone will give it a much better atmosphere. You also may want to turn up your graphics quality so anti-aliasing is on, that way the images will show the thinner parts more clearly. I would also suggest changing the font of the surfaceguis to bold to make them readable.
“—main cause of the vibe is the lack of materials and lighting. Those things alone will give it a much better atmosphere.”
Yes, I thought that was the exact reason why it looked so lifeless and dull.
This room gave off a really boring vibe.
The thing is, I have literally no idea as to materials and lighting.
Though I want to remake it, this is my lower priority as it’s just a side room, but I still want to remake it to the best extent possible.
Well, for start, try just copying the default lighting settings from a new place file and go from there. As for materials, they’re fairly straightforward and you should be able to have at least some idea of what to do.
Here are a few suggestions for materials:
-Concrete for the walls.
-Neon for the green stripes (or SmoothPlastic if you don’t want the glow).
-Concrete for the floor.
-Metal for the machines. You could accentuate some of the details by giving them a diamond plate texture.
That’s just kind of a base idea, and feel free to tinker with everything and change it up.
Also, a quick sidenote, don’t overuse the DiamondPlate, no matter how tempting.
Diamond plate? Give it up? Oh man…
It’s kind of been the thing used widely in my creations…
As for the rest, I’ll be taking them into full consideration…
Here are some images to possibly make you cringe

UPDATE || took in some suggestions and I’ve done a little bit of editing with things.
Modernization will come.
Here an example of a underground place I did a long time ago
Its not great but It can give you an idea on how to use materials to give the place a more modern roblox look
Those are actually some really good uses of diamond plates. You do a great job of using it to accent and not fill.
The lighting obviously needs more work.
Looks better already! For the lighting, try out these settings: (I came up with these based off of a similar game):
Here’s a quick explanation for everything:
-Ambient: The shadow color. If there was no brightness and just a hollow black box and no light source, this would be the default color.
-Brightness: The brightness of the sun, which shouldn’t be too relevant for an underground room. But if you feel like it’s too bright, you may want to consider lowering this to prevent light bleed.
-ColorShift_Bottom and ColorShift_Top: I’m going to be totally honest, I’ve never used these and I have no idea what they do.
-GlobalShadows: This enables/disables shadows altogether. It should be on for obvious reasons.
-OutdoorAmbient: The general color of the atmosphere. If you feel like it’s too light/dark, this is what you change for the most part.
-Outlines: These add an outline to all of the game’s parts. Some people like 'em, some people hate 'em. I think your project might benefit from these because they will accentuate the detail on the floor and machines.
IMO the 2010-vibe comes from the monotone colors and the flat edges of everything. I would try the following:
You can use this bomb I made as inspiration:
Aside from the core dynamo and wires, the build itself is pretty simple. It looks up to par with modern builds though because it uses proper color contrast and avoids flat parts with little variation.
But if instead of walking straight you take a right turn, you will end up on a base plate that is very 2010. 
Thanks for the incredible tips! 
I’m going to scrap the room and focus on making it better with all tips in consideration.
I know it isn’t as creative as what the other dudes have been suggesting, but there is nothing shameful about building things off of pictures as well as adding your own improv to it. Sometimes you best improve that way.
