I think your clever concept would have been strengthened by more evidence of beer in the empty glasses, but I guess photography makes you so thirsty that you needed ever drop;-).
I like the idea, but the other glasses look too clean to me, like they haven't been used, which sort of contradicts the title. Looks a bit out of focus too.
whoever pulled that pint needs shooting :) I like the idea, the composition is ok, as are the colurs, lighting and focus. I feel this image and title would have also worked well in the humour II challenge.
I like the broken pattern, I would like to see the front of all the glasses somehow, If you scaled down the lighting I think that would inprove it also, but still a nice photo
