Thanks for your submission. It's nice looking. I especially like the "sun" peeking out from behind. I think it may look a little too "corporate" though. We'd love to see a drawing representing our company next to the name. We're not opposed to something more playful.
I think you're headed in the right direction with #12. I like that in the bottom, it could be viewed as a book. I think we're looking for more of a pictograph (apparently that's my word in people's feedback today), so the book is a step in that direction.
I like your use of shading and the blue color, but maybe change the gold to something a bit softer to the eye?
