Cool stuff! Haven't tested it myself but it looks like fun.
I can tell from the screenshots you used color variation too which makes me happy(the pillars are different shades of grey).

Only complaint I have based on looking at the screenshots is the design of the structures. It doesn't look very solar based to be, more like an evil and dark kind of temple. I also would have opted for a much warmer kind of orange rather than that piss-yellow shade.

Neat!
