Hi: Well, it's obviously a very abstract representation of a hookah. In my research, I discovered that there are many, many styles of hookah -- from quite simple to very elaborate. While sketching and contemplating your logo, I noticed that the curves of the word mosaik standing on end roughly mimicked the curvy shapes and elements of a hookah: windguard, bowl, water jar, etc. And the curving shapes extending from the dots of the "I's" represent the hoses.
It's not meant to be a literal rendition. If you google "hookah bar logo" you see so many designs that use a fairly exact illustration. I wanted to give you something unique, alluring, and elegent -- I hope I've achieved that.
Please do let me know if you and your partners have any other questions, or would like to see additional revisions.
Cheers!
