Need help with dark spiritual attic

Hi everybody,
I have started my second UE4 proj. Its is a simple scene of a dark attic where somebody is making those ouija board spirituals. I have created some of the props. Cinematic quality
Production lighting
Archviz lightmass settings
All objects are 128+ lightmap resolution
Textures are 2k/4k

Maybe I became used to this project, but I feel like it is missing something. Really, like it is so CGish… I was aiming for a more realistic look.

Any secret weapon on how to make it look better (even if it is now fully packed with props now)

Many thanks!
