I'm not sure this could be more than one image because it's a moving subject (and believe me I tried)... but I do see a depth of detail that one gets from HDR so I'd call this a clean success.
This is totally unexpected. I like the blur of the passer-by. Would it have looked any different had you adjusted the curves/levels? I'm craving a touch more of the shadow and midrange tones, since it isn't a high key. I do like it though.
