This was my Equestria Daily Artist Training Grounds submission for theme 30: Previous Themes.
Any previous theme was valid for this one. So a handful of us decided this means we should do all the themes. It took a ton of preplanning, but I managed to fit every single theme into a single 5 panel page AND continue the narration. A full list of the first panel in which a pony fulfills the condition of a theme can be found after this little blurb. This was a really long, exhausting endeavour and, as usual, ponies in the distance are really hard to detail and not have them look like blobs. I was feeling a little off that day too, so I had to erase and redo a bit more than I anticipated, as well.
