I'm glad you are on a roll with the art.
No one makes art that everyone will love. It's always not someone's cup-o-tea. Like you say though, that part doesn't really matter. Sure it's nice if people like it, but it's not exactly what it is all about at the core of things. The best part of art to me is what it does for me on the inside. If some others like it, that is very happy "icing on the cake" as they say.
I'm not sure why you worry about down votes, especially on art. The only downvotes I've ever seen on things like that is where "someone" is downvoting "someone else" that liked the art or post and it is not personally against the poster. Unfortunate as that is, sometimes you just get to be collateral damage LOL.....such is life.
