I really like your ideas! I love #49 and 50 and I was thinking maybe you incorporate the circle with the tooth into the O. I'm gonna study them some more but wanted to go ahead and give feedback
Thanks for the feedback, Well as per the rules of logotournament, we cannot copy other designers idea, i think the other designer incorporatd the tooth in 'O' in his design first, so it will not be fair to copy his idea,
but i do not know if it was your idea or you communicated him to do the tooth in 'O', if it is your idea then i can incorporate it into my design.
