Such a cool idea, and brilliantly executed. To me these work because each shot is good in itself - composition, DOF, focus - put together the proportion and framing is balanced, and the final images are interesting, and slightly funny and grotesque too. The slightly abstract nature better represents how you take in a stranger's appearance, impressions of details, rather than steady stare a full length portrait implies. The uniformity across the series works well, it would be great to see these in a gallery display.
There's loads more good stuff in both photostream too.
I love flickr, but it really does distract me from what I'm meant to be doing.
