i just want to ask: "what is your marketing objectives?"
it's quite confusion when i saw the four ads together.cuz the first and the second ads, you are talking about "征服",it's a great idea, but according to cokecola company, they are already the second of the world. pepsi is the first.
so, they will try to catch up! what they need is not just "bulit a strong brand image"! they need to "hit the sweet spot"!
sure, the first one is better than the second one. it has good images.
can you think about better background of the third one? i like the tagline, but the background is so normal.
and the problem is the last one. it makes me confused. cuz i thought someone is seaking for the coke, but according to your tagline it like something else..................
maybe i am just dull.
