I agree with the others about how well this pairing works -- of course it would. Now I can only wonder why there isn't all sorts of Trelawney/X Lovegood fic and art.
It works so well to frame them with a "crystal ball." The textures, colors, composition are all really effective, but what I like best of all are their hair (untamed and so suited to them) and Sybill's expression. In canon, she annoys me, but not here. Definitely not here.
