We have brought our choices down to these final 3.
#1 We like it but most of the feedback we received said it looked to much like the medical symbol. It's actually a river that turns into a snake.
#2 It differs from #3 because the R in reptiles is "open".
#3 The R in reptiles is closed, we did this so we could se which looked better.
Thanks for your vote!
