My first entry - sorry I've entered late, I've only just worked out what I wanted to do to portray your brand. Your demo film is superb - congratulations on that.
My concept is a W which is customized (so it's unique) to include the two inner uprights interlocking, symbolic of the union of marriage. The reflection of this W is meant to look like the reflection in a polished white stone surface, thereby bringing some meaning to the logo.
Gosh, I really wish you hadn't jumped in this late. I love the concept of the intertwining W! Let's see if there's time to flesh it out. First of all, I just posted a long message in the main comments section as to my reasoning behind what I have listed as my top 4 right now. Please read that. With that information, perhaps we can adapt the intertwining with the other elements I like about the leading contenders. I'm not positive it will work, because my initial impression was of the medical symbol of two snakes intertwining - but we can try. It might be difficult but I think this W is too tall and narrow - I understand why, but could you give it a stockier stance, more like the top 3 designs? Maybe it could intertwine at or close to the top of the center of the W. I'm not too keen on the reflection you have that's shaped like a bowl. Can you tone that down a bit? I think the rest of the notes I'd give you are covered in my comments on the main page. I'd like to see what you can do suede. Thanks for contributing!
