Krita doesn't do the impasto-style stuff, though with the Digital Atelier brush preset bundle, you can come close. There are a lot of brush engines, and the brushes are very customizable. And it's free (donations accepted, if you want automatic updates, go to Steam or the Windows Store), open source, and there are no in-app purchases whatsoever.
