Fellshrine Ruins way too bright!

I feel like the Fellshrine Ruins are... well, as the title says, way too bright. It goes even beyond looking cinematic, it's almost comically brightly lit, ruining the atmosphere it had back in The Day™

A visual as reference:



It almost looks like the map has some sort of mat_fullbright enabled.
With such bright, yet flat lighting, there's almost no real feeling of atmosphere in this map, minimal as it is in regards to the rest of the game.

For comparison, here's an older version of the same map:



Much darker, less intense on the eyes, and it feels like you're truly in the crumbling ruins of a place of sorrow. There's also some semblance of a need for Light Radius.
