I have been thinking about the example I used in my post a couple of days ago when I was talking about my own fussiness about certain details of my and other people's art. I said it bothered me to see trees that taper the wrong direction. Well, sometimes I make these rash statements and then later I wonder if I even really believe what I said. Kristin left a really great comment saying that what bugs her is when art is done without intention. Yes, I think she really nailed what I was getting at. If you missed her comment I recommend going back and reading it. Jarring visual notes in a piece of art can work when there is intention. And I'm sure I would find a painting of fat-at-the-top trees intriguing, if intentional and part of a pattern of distortion that the artist was exploring. It is when the thing is supposed to represent a form and misses because the artist just wasn't very observant or mindful that the jarring effect lets the rest of the work down.
Well, this is, of course, just me rambling and wondering and not directed at anyone in particular. I googled "abstract trees" to see what I would find. Most of them were tapered in a naturalistic way. A couple weren't and looked unintentional to me. But, wow, what great trees I saw! Here are a few favorites.
