It's inconceivable why anyone would come across a path in the woods, and just when the clearing is in view, plop down his easel and paint the scene with 5 leaning trees in the way.
5 measly trees. You could just step around them and paint the scene in full. Or you could just imagine them not there, and paint the rest of the scene. But no, you decided that this was "it." This was the perspective you wanted, and you painted those impossibly leaning trees in a part of the forest that was apparently ravaged by hurricane-strength gale winds and/or loose soil.
This is frustrating enough to induce balding.
