I can't see entries 14 and 15, but 11 and 12 are very nice, but they remind us too much of our old logo. Hoping for a snappier, popping out logo. Something appealing to a youthful audience. Many of our professionals are young and are attracted to a younger style.
Now I can see all your entries. Must have been my computer. Sorry. For some reason these images remind me of a stamp that goes on an envelope. Can you try outside a circle concept and see what you come up with?
