Hi Yeya,
I loved your last options, they were beautiful. But as I decided to go in a more simple and refined direction, more of your earlier work made it to the top of my list for the logo (as far as my personal taste, you were right on).
As an overall concept, I like #s 14, 15, 12, 17 & 13 the best
My favorite colors themes are: #32,34,15,19, & 31 (32 is my favorite and so on...)
Thanks!
Mindy
