These screenshots are really dark, pretty hard to tell what I'm looking at in places

 

Not the issue, it's the fact that everything is one color, a darker color at that which makes the shadows even darker

I think white emissive overlays could give your lights more unique shape from one another. I recommend subtly changing the floor's color to be different from the walls. Cool shapes!

 

Emissive is an overlay that you can put on things like wall or block pieces. It makes the object glow brightly, so setting the overlay to 1 works well. Such objects can be phased just over your light sources and give them more defined shapes along the walls. Give it a try, they have many uses.
