Ha! Nice "featured" photo. Like how in the thumbnail it appears that it will be a cute, semi-risque shot, but once you open it you start to wonder about the unshaven legs and the sort of masqueline nature of the feet. Self portrait? ;)
First Impression - the most important one: Interesting shot .. I don't think many people would see this as meeting the challenge (and they didn't from the voting) but technically not bad.
Composition: I can make out some nice horizontal thirds going on here ... not quite the verticals .. but hey not really room for them in this small room shot.
Subject: First instinct - where is the footwear ... I think is may be what a lot of people thought. Although it is a take that not many would have thought of ... I think it is funny myself .. but I have a warped sense of life.
Technical (Colour and light): This is where I think you excelled .. good crisp colours .. great lighting ... really nice natual feet/skin tones .. works for me.
To grow its vote?: Meet the challenge .. put some footwear on apart from knickers that is ... :)
Summary: Good take .. pity others didn't see it .. but you always have that unique view of life.
