I’ve found an interesting YT channel, Logos by Nick. He’s got a lot of Inkscape tutorials, many demonstrating specific techniques that I’ve been looking for. I might spend a few days practicing some of the more useful ones and then maybe incorporate them into my LearnSquared course.
I checked out some of the imagery coming from the Apple TV production of Foundation, and I’m pretty sure the ‘prime radiant’ is almost exactly what the LearnSquared course is aiming to teach. If the tutor didn’t work on it directly then I bet the person who did has done his course.
