Entry 21 is a great design base - can you try and make a "Z' instead of the cup and also just have the word "ZEBRA" in red below with the slogan " Drink it Black or White " in black underneath that.
Many thanks for your appreciation, i uploaded 3 new logos, but really sorry for not replacing Z instead of the Cup, because there is another designer who did this Z in the texture, but i did a few designs hope you find them well...
