@Rags: Thanks. I have a lensbaby, but didn't use it here. I find them really awkward to work with - difficult to get the sweet spot of focus actually sharp (although the new version is supposed to be easier). This was done in post, using the Alien Skin Bokeh plug-in.
Part of me really likes the blur and concentration of focus, but then if I look long enough it doesn't quite feel right, I may have preferred it without. Wonderful nonetheless.
