Looking good! I had a feeling (judging just by the windows) that this is not a US-prototype building. It is amazing what types of equipment hobbyists own (or have access to). Having access to a laser cutter (and ability to design items to be cut on it) sure makes it easier for someone to build unique structures.
I only have a Alps printer (for decals), lathe, milling machine, and a mini drill press. Sort of makes me feel inferior (in the tool department).
One thing I would have done differently is that I would have scribed tile lines on the lower corner pieces, where the interlocking ends are visible. That is an easy and quick fix, which would make a big visual difference.
