What's some artsy freewares that you use?

I've been learning how to use some freeware softwares as of late (5ish? years), such as Krita, Shotcut, Gimp, and using any site that will allow me to make marks, such as flipanim (rip gng), magma, scratch, and others. I'm curious to see if there are some fun ones I should try out on my linux setup, and I'm starting to get comfortable with Krita, and would love to try some more :3

So, does anyone here like to draw on freeware as well?

i only use azpainter3, it's been my favorite since it was still in like v2.1. you'll have to build it yourself, so it's not super beginner friendly if you've never hunted down dependencies before, but it's so easy to make your own brushes in it, and it's lightweight and has the perfect amount of tools - not so many you get overwhelmed, but enough to get what you want done.

For animation i recommend opentoonzits not very family friendly but pretty powerful imo >:)
