Thanks for your entries. Regarding #10, we like the "global" idea of the circle. Could we see a different color scheme?
Regarding #3, we like the design aspect of it. Different from everything else.
Regarding #2, we're not sure. We like the fact that it has people in it, but it reminds us of either soccer goalies stopping a ball, or the face of an alien.
Regarding #7, we like the concept of using the 4 in there, but not that particular design. Could you think of another way to do it with the 4 in there somehow?
