this was the first. i really like the biscuit background colour with the coke red. the waves are spread over ten layers to ensure the overlap covers each wave's tail.
i experimented with an additional bottle shape here, but i think it is too dominating over the smaller bottle icon. you have to respect the bottle shape, it's one of coke's best assests. i'm pleased with the colours in this one too. i'm working on a combination of them both.
