I actually don't keep anything stored on my local laptop but I do keep a drive of drawings and artwork I find from my favorite fedi artists on a backup drive. One of my favorite artists when I first got on Fedi is Grayp and they ended up mass removing a ton of their drawings. I am sure it was to free up space but I really liked them so I started keeping copies of the drawings I like from now on. I've been looking at them recently to get an idea of how they drew them to begin with.
