Hey there,
Appreciate the feedback and checking out my work!
While this is finished now, I will take the time to experiment with more atmospherics, while the scene is already quite atmospheric, I can see your point.
As for the light on the left, I dialled it back with low attenuation and no shadow casting (coming from a game dev background) this was habit from a performance perspective, the red light is the key light here, but Iām no lighting artist 
Cheers!
