First impressions are that this rocks - it'd make a great poster!
Technically this is well done. Composition and POV are great to provide enough emphasis on the shoe while not allowing it to overwhelm the shot. Your lighting is superb (I wish I could master lighting like this) and the unnatural processing works here. Viewing this with the watermark is a shame as it does detract from the shot but them's the breaks.
Artistically this is great. The POV used gives a great sense of drama and scale. There are some distractions that I'd have cloned out. Just below his right eye is something (from the glasses?) that makes me think he's got boogers! Also, the reflection in the left lens is a huge distraction from both the subject of the shot (the shoe) and the overall feel of the shot.
In summary a great shot that was worthy top 10 material.
oh Dave Hill I thank you for bringing this style to the mainstream. the high-pass sharpen made some crazy halos on the right side and by the rear axle - actually not even sure anymore if you could fix that in the DPC ruleset. Either way I don't care because the overall effect is awesome. Print it and frame it :)
