I've been wanting to switch operating systems on my work notebook, but I've grown too used to Clip Studio Paint, which is not ported to Linux OS. So i decided to pick Krita and try out what it can do animation wise, and while it's tools are much simpler than something like Blender, Toon Boom Harmony or OpenToonz, they are quite simple to use and fun to doodle.
So I made an animation loop of a character of mine wagging his tail, time spent was about 3-4 hours.
