Dark Hallway Scene

Hey guys,
Here is a wotk in progress of mine, it’s a modular dark hallway scene / level… The scene is textured completely with Substance Designer to go easily from like brand new and clean to old, dirty and rusty.
The scene is not finished so far, i like to add some dirt, rusty leaking decals and some more side rooms. Any constructive critique is welocme esepcially for the lighting…
