I like, I like. You said in reply to the below comment that it was a highly developed species taking over a planet. But the ships would be a little large in comparison to the planet and the weird structure that seems to be holding it in place. I say it is a beautiful idea (and nicely composed and painted!), but I think that the planet looks too small in comparison to everything else OR that the structure doesn't look large enough as I presume one light = 1 window. Just my opinion.
thought that it was a planet overtaken by a highly developed species, but it could also be a planet factory or a starship with a planet in it or something else o_O ^^
