NICE ad. Love it

Because everyboody would have drunk it all!
Nice and clean!

Crisp and clean. The image portrays the abstract notion of 'light,' but then your text introduces the concrete notion of a table that is nowhere to be seen. A simpler message along the lines of "Kabooza, the truly light wine" might work better. [An aside: Why is a 'light' wine a good thing? Is it especially appropriate for particular occasions or with particular foods?] The label is classy and sophisticated, but while its border matches the curve of the bottle exterior, the illuminated-K logo and text do not.

Bottle design is very good. shadow you should compress vertically at-least 50%.

Well, you just changed a table for a shelf, but the message is still the same...
Light is light, but not in excess!!!
@Dan: I don't understand about wines - I don't even drink - but I suppose that a difference of a white wine and a red wine is clear, at least for me; I think that the white one is lighter in taste than the red one. Soft and smooth... Am I wrong, author?

Shadow isn't too convincing... gotta agree it needs pulling in vertically... also just a nit pick but the shadow wouldn't be oval either... based on the light hitting the bottle...
oh one more thing... the message might be conveyed better if there was a bottle either side of your 'brand'... just to show the difference visually... ??? just an idea!?!...

I like the concept, and it looks like a real ad, so kudos for that. I will agree on a few minor technicalities: The shadow seems a bit off (perhaps the vertical compression suggestions will work) and if one looks closely, as DanLunberg suggests, the logo and text on the bottle don't match the curvature of the label itself. Perhaps a very slight warp on those elements would resolve. Either way, it's well done, conceptually, as well as execution. Good luck author.

Very nice work author with great slogan...best of luck
