We REALLY like the direction you have with #14. There is something VERY clever about it. We like the artistic aspects of it, plus it has a font-like characteristic. The 3 circles above...we like them, but it feels a little like there are 3 of us - not 2 of us. Perhaps play around with that a bit? And maybe increase the size of the 2 W's a little? They seem a little lost compared to the aspect in the middle. But we do think you are very much on the right track!
As for #19, its not really the direction...so we would put that one in the category of not liking as much.
Love it overall though! Keep them coming!
