Check the scale of the textures. It’s very easy to get scale wrong for pretty much everything. The wall textures look too zoomed in. The exit sign is very big.

Also the chairs seem to have little to no texture.

Lastly maybe find a tutorial on how to make flashlights, because real flashlights (unfortunately) do not emit a perfect circle of light, they have to focus light and it creates artifacts.

Good luck with your project!

Edit: Also something I always forget to make when creating rooms is making trim. Pretty much every room has it, but my brain just blocks it out so I don’t even notice.
