Thank you Pauljs75 and Holyforest. I thought I'd try your suggestions Pauljs, and I have to agree that I like the lighting better since I did so. I dialed down the ambience to almost 0, and took a little more brightness out of some shaders. I also boosted the neon and street light a bit. It made everything look a little more "noir", and I like it. Thanks for sharing your ideas!

This is just incremental stuff. I am almost finished with the rest of the block and will post a new pic with that stuff soon.
