Here's a closeup shot of the balcony with Head Mistress Athena's table and soon chair with all of the other amenities to come.
This zoom in perhaps shows the advanced lighting effects I wouldn't have as easily with Kerkythea and sketchup. Between each column on the ground floor hung from the balcony.... mezzanine?... errr 2nd floor to illuminate the target practice area is a single area light, three in total, and each light interacts with the others and even partially lights up the steps to an extent.

The ceiling lights also blend with the target area lighting, casting multiple shadows, and something that would have made my old tabletop PC crawl from what was being asked of it. True my current laptop is far more capable...even for a laptop... but the three overhead lights mixed with the floor lighting withing Blender was a simple matter for this app.

And even if I add more complexity to this scene, with candle lit wagon wheels hung from the ceiling, and some torches on the walls, with windows cut into the back wall as well, I don't think it would be asking too much of my laptop and blender. And that I really like!
