So I set out to vectoring the glorious Surfing Pinkie, and decided to do Celestia while I was at it. I certainly didn’t know what I was getting into, as the whole thing has taken around 8 hours.
 
I knew Celestia was going to be trouble, but the parts that I expected to be tedious were not, and others I hadn’t given a second thought took half her time (about 2.5 hours).
 
Pinkie and Gummy were a whole different level of work. Even with a 1080p capture, there’s a lot of details that go missing, a lot of curves that get smoothed, so they have a lot of improvisation and projected redrawing on my part, so some parts are going to look odd. Specially Gummy whom, as I found out, doesn’t have much around in the form of reference material.
 
I will upload both separately, of course:
