Some from other collections
Some from The new Clip studio paint assets feature
I didn't create any of these brushes, but I did hand pick my favorite brushes and sorted them into folders for easy importing for when my PC dies again.
I also found the best soft painting brushes to draw moe anime style
I found the best Pen for inking manga, it's like texture pen except much better. It's so good it's one of the highest rated brushes on assets.
All brushes in this collection were "free" with no strict terms of use besides the obvious "don't repackage and sell for profit"
