If, on design #6, you could remove the dot in the middle, and pull the yellow and blue close together into a ball I think that it might look good. What about in a hexagon shape?
Is there a way to combine #76 and #77? I like how #77 has the smiley face but I also like how #76 is colorful over the "joy" portion. If there's a way to take the graphic portion to the left of #77 and put that with the way you stylized "CableJoy" on #76? I think we are on a great path!
