Day 11 is simply labeled as casual setting. When I read these prompts initially I thought that meant drawing scenery. I don’t know, it might, but I’m not really good at that. Besides, I thought drawing a casual outfit would be more interesting, particularly since some of these characters are never really seen/drawn in anything like that.
Nightshade’s civilian identity Ryaneyu doesn’t show up much in Angels of the Night. She prefers wearing her Nightlord uniform as it’s a point of pride to her. On the rare occasion that she’s in casual clothing, this is what she looks like.
