I hope I gave you some different concepts to consider. Please leave feedback on individual entries rather than in the general public discussion area... that way we get individual emails to notify us if you want to see variations.
I like #27 the best, due to the multi colored hands. That gives it depth and variety. I like #31 for the people holding hands and the concept of all joined together. I like #28 for more whimsy and fun. It looks a little too like an Olympic logo. Our client is looking for something a little more whimsical and less rigid or formal. Thank you for your entries!
