There is something about the person in #2 and #3 that I'm not crazy about. Left arm looks like it is in an awkward position, and I don't like that you can see a definitive line at the buttocks. I do like the multiple colors used in #1 and #2. The font choice is good, although I might pick a slightly different font solely based on the G in Dupage. Thanks for your quick response.
Spiral in #8 and #9 is too busy for me, as are the lines between branches in #11. The two with the obvious female that I put as not interested looked to naked.
