David Revoy (of Pepper and Carrot fame), shares a pack of Krita brushes under a CC0 license. These brushes reflect his personal drawing style.
You might find that some of these brushes are similar to official default brush of Krita: their aspect, their usability and their thumbnail design. That’s because I designed the default brush of Krita and even if my taste evolves a bit, my classic and way to solve problems remains the same.
The goal of this list was for me to reduce the selection of the brush to a more compact set. I selected the one I daily use to fit into two columns on my quadHD monitor. I also wanted to them to be organised by group of colors to pick them faster and take better decisions while painting. I have now a group dedicated to “details”, a group specialized into “glazing”, “texturing”, etc…
This pack is tied to my “visual vocabulary”. I’m curious if there are “words” in it that will become part of your. I’m sharing them this time under CC-0/Public Domain license. It means you can do what you want with them: commercial, tutorial, teach, etc… do exactly as if they were part of the default brush. They were named to also blend within the default.
