Hard to differenciate the front glasses from the back glasses, they kind of blend in real well with each other. I can definately see them though, and there are definately 7 of the subject. I don't like the background much. the blue is distracting, there are distracting shadows from the glasses, and your horizontal line is tilted slightly to the right. needs a very slight left rotation to even that up.
The arrangement is a bit too tight, and there is not enough of a contrast between the glasses for this one to be visually impacting enough. Maybe filling each glass with a different colored beverage might have worked to your advantage.
lighting seems a bit harsh from the camera flash, also wish the background were farther away to isolate the glasses more. bright and sharp, nice focus.
aren't those the Calgary Olympic glasses from 1988 that Petro Canada was giving out??
decent setup, although not perfectly centred. Lighting could be a little less harsh to make it "pop" a bit more. I think a plain background might have worked a bit better as well.
