There are very interesting brushes in krita that I couldn’t find a use for. And these brushes are the ones I have 0 idea what to use for. I’d be very interested to see other people’s POV and if possible artworks that used one of these brushes!
They have very specific use, like for pixel art, and some of them are not meant as regular brushes but more like editing tools to liquify, blur or change the colors of an image. The bottom left ones can be used to create a base layer with color variation to then refine with other brushes. I use the sketch brushes sometimes, as they can be fun to use.
