The mothership has a top-heavy design; I've got an image of it from below but it's less interesting, especially at the shallower angle I'd have to use to replicate the screencap. This angle gives it that flying saucer-y look that it's based off.
Day 1185: Mothership2
Just slammed down some flats, not worth an upload.
Colourwise I want to take my cues from this glossy little thing; a very blue space and a very glossy, reflective material. No idea how I'm going to make that work though. I think I'll start on the space and do the ship itself last.
