We really like your #21 entry....we will be re-ranking soon...but would love to see this with "less pointy" base/ roots of the tooth. Also please drop the word "GROUP" -- Great Job!!
By the way-- I just got that it was a "G" and a "D"...Very Cool! I will be reviewing these with 2 other people from the office soon....so we may "re-rank" after we talk...I really like this one!!
