Yes, and the anal people are not faint in awarding scores of 1 to those who in their very narrow opinion failed to meet the challenge. Any kind of feet work for me if the shot is good, but expect a lot of attitude if those feet are not human.
Personally, I think ALL feet are feet.
Otherwise they wouldn't be called feet!
I am sure though that there will be many voters who opt to view (and vote) on a narrower definition than what is actually outlined in the description.
My only criteria is that the image is appealing/ interesting/ well conceived.
I get fed up of pictures that fit the challenge but are just plain boring. NO I CAN'T TALK, most of mine are crappy but... I'm just saying what I like as a voter!
