Clip Studio Paint It is my "workhorse" choice for illustration and sketching. Starting from its ancestor IllustStudio I've designed lots of tools which are the pillars of Daub Brushes.  DAUB tools are designed side by side with traditional media artists, digital professionals and common users too, to give the most natural feedback and to be funny to use, balancing responsiveness and quality.  All my Clip Studio Paint brushes and the following exclusive sets are included in the Super Bundle!
