well, i used painter 12, and i found out that it has weird behavior sometimes. i used an acrylic brush, i think... a dry one. at first, it left several marks, like a strand of hair, but the lines were parallel and it didn't look natural. so i decreased the size of the brush, and it started drawing with fewer strokes, sometimes, when the pressure was weaker, a single stroke only. i could have used a pencil as well, it would have had pretty much the same effect. it's painful for the fingers, but i guess it was worth it. however, painter has its mysterious ways. sometimes it acts totally crazy, shortcuts don't work, brushes paint painfully slow, sometimes brushes don't even paint the way they should.
i don't like that the brush strokes here are somewhat uneven, so the hair looks unnatural. it's well detailed, that's fine, but the highlights are so messy
