I've been purely using the basic round mixing brush in Clip Studio Paint for basically everything so far (lineart, colouring, effects, etc.) and I feel like it's not quite doing the job for me, especially when it comes to pen pressure controls and stuff (that might just be because my screenless tablet is 5 years old). The other basic brushes are the same deal. Other than gimmick brushes I've found, I can't find any good lineart brushes. I'm flat broke so I don't have clippy or the premium version of Clip Studio. Does anyone have any suggestions for downloadable lineart brushes I can find on the marketplace that are free?
