These are brushes I use for Paint Tool SAI!
I like this brush (“BIG SOFT”) for a lot of rough work and shading, got it from one of my favourite artists ever, @velinxi
I use this brush (“no pressure”) for a lot more small details, it has no tapering and it’s pretty good for outlining and tiny areas of shading
Pretty sure “Acrylic” is one of the preset brushes in Paint Tool SAI, it’s my lifeline when it comes to blending and shading
I don’t use “Crayon” (another preset brush) as much anymore ;; but I’m very fond of this one, I used to use it for lineart
so yeah! ask me questions if you’d like, and also have some examples of the brushes in action
