The idea is great! The background is too busy and therefore distracting. I also feel WB problems here. I would show more of the text on the old bottle and I miss the top of the bottles very much. This subject cries for a portrait crop. I think noone needed these bottles anymore, in your shoes I would have taken them home to make a nice composition. I would have filled them with Coke as well, but at least the new one. Use diffused light for glass, because reflections can be very distracting and cause overexposed areas sometimes.
Idea is good but the colors of the background are distracting and unattractive, wish you had just placed the bottles on a white tablecloth, one lying down, one standing for example....
When I thought about this challenge, I thought of about 20 different ideas, and each and everyone of them have been represented here. This, however, is one I did not think of. I like this. Good going. 8
I like the positioning of the letters forming one "Pepsi" between the two bottles. This could've been improved with a simple, solid color background. The underneath of the table and the background furniture is distracting.
I don't remember seeing a Pepsi bottle like that and I'm pretty OLD! So your subject is interesting but the background is a bit distracting.IMO this would have been much better against a solid background with more emphasis on your cool subject.
I shot a rendition of this too but my wife liked my current submission better...I had an old circa 1970 one gallon Coca-cola Syurp bottle and two newer coke bottles. Good luck
