Is it just me, or was this inspired by Ramiel from Neon Genesis Evangelion? Both the correct shape, and the atmosphere, they match NGE a lot. [link] Also, rainbow if you consider the Rebuild series...
Welll Ramiel is an octahedron, while this cube is a cube. ('Cos I'm pedantic.) But they certainly share the similarity of giant geometric shapes in an otherwise realistic landscape. Check out Dali's take on this theme [link]

Beautiful tho, great job as always.
