#12+#11 : we would like to see these designs with the logo of #13, 13 looks a little shorter and wider, giving it more of a K appearance. We like the abstract logo, pleas continue working on this idea.
#13 This logo is the best, we would want to see it in different layouts. Also we love the little bright blue shine in the middle, the gradient is good, however we would like to see the end gradient with a little more dark, richer, blue.
Please make sure the font is big enough to read, We like the font used in #11.
