rebelle 5 is on sale for another week-ish and it's a pretty fun and focused tool for emulating some parts of the traditional painting process (i won't pretend that it feels like the real thing, because there's no way it does, but the pigment mixing mode is nice and some of the brushes feel resistant to overdetailing in a very 'analogue' way) so i recommend it for anyone who likes to paint on the computer
