"Just getting started", I feel the same with the guitar. Been playing since I was 12, 40 years on with quite a few breaks still love it and having fun will never be a pro! I work with loads of great artists, I really can't draw (but am according to the deeds of my apprenticeship a qualified draftsman!) but still love to doodle and sketch. The awesome artists I teach and work with always amaze me, mostly the really good ones always have a sketch book with them and always doodle. This is the key, love it, practice it and enjoy :-)
This is going to be useful for many things in my teaching. I've just got my students to install Rich / textual for my python coding course as I've featured it as one of my Modules of the week. https://nccastaff.bournemouth.ac.uk/jmacey/msc/PipeLineAndTD... So this will come in handy. Great work.
SeExpr is great and used a lot in animation / shader development in things like Renderman from Pixar, it was great to see it in Krita https://wdas.github.io/SeExpr/
Years ago we took one of the happy birthday tune cards and connected it to the floppy drive hinge on a PC, the developer was convinced we had installed a TSR program to play it every time he inserted a floppy, not realising it was a hardware hack. Weeks of fun until he found out.
