gallery talk

Variations on an image from tonight. Which one(s) work(s) best, if any?



gallery talk --
a man watching through the glass
blends into the night



gallery talk --
the panhandler outside
watches intently



gallery talk --
the audience watches
a homeless man outside



shielding his eyes
the homeless man peers in
at the artist's talk



gallery talk --
the panhandler outside
shields his eyes to watch



One of the key questions for me is, is it obvious enough what the phrase 'gallery talk' means? Is it clear that an artist or a curator is giving a public talk inside the gallery about the work on display there? Or is there a better way to set the scene? So much to consider for such a short burst of words...
