I agree with the below comments. The eye doesn't rest on any one focal point. I think if the bottles were in sharper focus, and perhaps if their positioning had be changed a little this would have popped. I like the idea, and there's definitely a festive atmosphere evoked here. I think from an emotive standpoint, there's good storytelling, if only just a snapshot of the season's festivities, and the pun itself is clearly defined.
I think you cropped a bit too close to the bottom of the frame, and that the botles bleed into the backround because of two factors, the lighting is too universal, a flash or spot picking them ou would have popped them forward; and the focus is too soft if the bottles were crisper they would have seperated more strongly from the BG which is nicely fuzzy.
The strand of lights woven through the bottle isn't cutting it, too subtle, either bigger lights or brighter lights (longer exposure and don't light the tree for part of the time?) could help, otherwise just loose the strand.
I think there's also a little barrel distortion here. Because of the low angle you have shot from the two outside bottles lean in/bend slightly, this can be fixed in PS.
As previously noted the background is the same intensity as the foreground, maybe lose some of the light, or increase the light on the foreground subjects.
There is no single part of the image which the eye wants to rest on, no real main object, maybe try an make a composition where the eye follows a line to end up on a bottle.
I think it needs more light from the front because the tone of the bottles is now the same as the background. The bottles should stand out a bit more, especially the part with the text.
I don't like it how the background works with your foreground subject, the reflection/refraction of the the lights in the bottle is too busy.
I like it. I gave it a 7 during the Challenge. The idea is great.
Maybe the composition is a little bit static: all the bottles are at the same distance, so they are the same height. If they were forming a diagonal rather than a pararel line it would improved the photo IMO. And in this way you should also could use a shallow DOF to just focus on one bottle.
