Mushroom Complex Facility - now furnished!

I recently built this on my private family server to use as a player operated mall. The interior is "gutted" - no decorations or furnishings since I plan to allow the players to build and decorate their shops inside the complex. There are four floors and it's designed so it can be expanded by stacking it on top of itself. If my family decides to keep their shops scattered about our world maps, I'll turn this into something other than a mall.

I aimed for a bio-luminous effect so it would look like it glows at night. Please diamond if you think I achieved the desired effect.

The screenshots were taken on the server using the default texture pack, but the complex is isolated in the schematic.

You may use this however you like on your maps, so long as I get credit.  I would love to see screenshots of how you used it.

Detailed feedback on the design is also greatly appreciated.
