Day 1188: Mothership6

Updated the linework and put down a lighting map. It helps to stop thinking of this as a finished products but a series of individual things that I don't know how to do, which lets me come up with better methodology. The lighting map is me sketching out the location and direction of light sources, which is useful and helped me avert a big mistake later. Also named all my linework layers; I'm in this for a while.
