Thanks for the comments guys. Roron, I haven't really intended to put in a band. Its pretty big but with all the doorway arches I'm not sure where to put them.
I've got another update. I spent about 3 hours working on this tonight. I finished cutting out the walls for the side rooms. My goal is to make the side rooms available as "alternate" sets for other locations (Tatooine Cantina for example).

As I was putting this together for a picture, I realized that it is quickly becoming too large for my table

Not sure how I'm going to address that yet. I can either make the side rooms smaller or keep them as individual walls that I can move around and place as necessary.

The walls were spackled and coated with a base coat of Delta Dreamcoat "Trail Tan" It was a wal-mart special acrylic paint.

With inspiration from the Bounty Hunter game, I've put together a balcony that I'm planning on attaching to the wall.
A couple of open questions I'll need to answer.
1. How to address the overall size of this project. Should I make the side rooms smaller and risk not letting them be "usable" for other sets or should I use moveable walls. I haven't decided yet.
2. What to do about the floor. Given the size, I'm leaning towards going with a roll-out vinyl floor. I'm just afraid it will look too "plain"
Any thoughts or suggestions would be appreciated.
