tl;dr - I'd like to note that I'm glad you brought this to my attention, anon, as I had deviated from the order which I was sharing the files when I'd posted that image. Your comment not only reminded me I'd done so, but that I also hadn't gotten around to labeling a few folders, which means I'm going to have to back-track some. Which means more pics for /e/!
