Interesting take on the challenge. I would have preferred to have at least seen some bubbles in the shot. I do like the setup, the lighting, and the composition though.
I like the rich tones that the jewelry box helps to create, it makes a nice foil for the black background. This tone also seems to be highlighting the glasses in an interesting manner and the focus is pretty good but where it a little crisper I think it would give the image more impact. The rings/box seems to be an integral part of the image so I wish it was a skosh more in focus. Also, I would suggest adding a bottle of champagne to help further the impression of an impending celebration. I'm afraid that I do not see this as meeting the challenge as there are no bubbles present that I can see - the absence of bubbles and indicating such with the title doesn't quite cut it for me in this instance. Had there been a wine glass or champagne or something liquid that I could say, ahh the bubbles are in there, then I could probably make the leap. I do like the idea, I think the composition is good - the tones are nice - the lighting is pretty good, maybe a bit too harsh on the ring box, but overall decent. I gave the image a 4 due to the lack of bubbles, bit of harsh lighting and the focus I mentioned, I would've scored higher had bubbles been present.
I admire your attempt here but the item in the box is nol clear and I am guessing it is a ring. Also, if this eludes to an engagement, you really should have used champaign flutes rather than wine glasses.
