I forgot what app it was (maybe flipaclip? idk) but I once took about probably a day and a half with all the hours put together (which actually took me almost a week) where I did a fully colored scene. And it was me turning and waving only. But I made it SUPER smooth or as smooth as I could and it looked like a real scene in my opinion mostly cause of the colors and shading. Sadly, I lost the file but I did show a couple of my friends amd family! Still, I'm sad I lost all that work
