I paint abstract art and I've sold a few paintings. I literally tell my buyers: "It's abstract. There's no top or bottom. Hang it whichever direction you like best." I sign them on the back for that reason.

As long as I've painted something that I like, I'm happy. If other people like it too, that's just a bonus. My abstract art is about evoking a mood or vibe. Or at the very least, something that makes you think "That's kinda cool" even if you don't have the vocabulary to express why you like it.
