Tried to recreate one of my favorite flat brushes from another program (I use it for sketching, lineart, and rendering), it’s not perfect but quite similar. The sample image (my OC) was drawn with these brushes + some post-processing (filters, gradients, etc.)!
Update: Previous brushes only changed color when clicking on the sub color option, the new ones should work with both main color and sub! Please delete the brushes with “error” on the thumbnail, I apologize for the inconvenience T.T
