Fantastic software!
I use it mainly for animation. I've used Toon Boom and Photoshop before, but Krita honestly has the easiest to understand interface, which can be customized to your liking!

I've been using it since 2017 but it wasn't until later I knew there was a Steam version. Honestly worth paying the five bucks to support the devs and get the latest version right away when it gets updated.
