This one was done after I’d started the comic – I hadn’t made any sort of colored concepts for angels, which really slowed me down the first time I had to draw one.  So I decided I would need to make a concept at least for dark angels.  This was basically how I’d been imagining them, but I realized afterward that I’d really, really need to tone down the blue when I actually drew them.  I also decided to confine the stars to only the shadows, instead of sprinkling them in all the centermost areas.
