Something I made nearly a year ago. It’s a basic tutorial that serves as a quick start guide for those new to MyPaint (workspace, canvas manipulation, keyboard shortcuts etc.) It’s a little outdated by now though, since the guide’s based on version 1.1. Most basic functions remain the same, but icons and sample screenshots might have to be updated.
The guide also features my take on a personified/humanized version of the program (I’m not the first though, I’ve seen other artists draw their versions of “MyPaint-Tan”). I might draw her more as a tutorial character if I decide to make more of these. You can view her current standalone pic here:
