In William's image and Joe's first image I see a characteristic of the Petzval bokeh that I don't like. (Don't get me wrong, I like both portraits - particulary William's (I would love to see a print!)) The OOF area of these photos seems to swirl around the center of the image. I find this distracting because it pulls my eye away from the photographer's subject.
I've seen this characteristic in other lenses noted for their ability to render pleasing bokeh (e.g. the Nikon 70-200mm VR). I don't know if it due to optical design, or some aspect of the subject and motif, but I suspect it has something to do with both. Perhaps there's a knowledgeable forum member who can lend some insight into this phenomenon.
