Need help with top down graphics

I'm currently working on a top down game which consists of rooms that are all indoors. I set my camera background color to black but this just makes my rooms look like they are floating in space. Anyone have ideas how I can make this look better.

Add a Black Plane at bottom of the your world and make it bigger than the world you are on it, like Water in almost all games and let camera render it and applies the lightning.

Try it out and let us know.

Thanks.

 

Yep.
Or add a large flat plane, under your stage. Then add a material/shader to it.
And then add a garden texture, or a nice grass texture, or a texture of your
choice to it etc.
