I like how #5 turned out -- emphasized more of the graphic by still has the name below. #6 seems too long, but I like the proportion of the graphic to the wording. And I like #3...similar to #6 but more compact across the page.
As far as the colors, the ones you picked are very nice...sort of soft...if that makes sense. I'm wondering what a slightly a darker blue and green might look like...a bit bolder look perhaps.
Overall, I like what you've created. Nice job!
P.S. This is the first time I've done this...how am I doing with my comments?
