An advert for 'water'

So here's the new project of mine... guys are launching new oxygen enriched water called "OxyAqua" soon and im in charge of the whole image thingy.

And here's the artwork that's gona be used for adverts.
Let me know what you think guys, i appreciate every single comments, it matters a lot. And as always, favs are hugely appreciated.

The space on the right will be occupied by logo and marketing stuff... slogan or something.
