It's about to undergo a complete redesign - or rather, a first design, as I never 'designed' it in the first place. Everything will be grayscale except the foilage. There will be lots of trees and curvey stairs and columns and other such things. It's meant to be a temple on the side of a steep mountain, so I'll be doing three distinct layers of mountains - Geometry in the level, geometry in a portal skybox, then finally the rendered skybox. Granted that I can figure out how to get rid of those lines. I know they aren't blend lines because they are black; blend lines just make a faint seam appear.
It shall be called 'Focus Mode'. Expect more soon.
