Great improvement in direction on #38. Perhaps being more defined like a piece of Lego or puzzle peice hooking to another one and a more identifiable key hole would be desirable. I understood the direction, but I believe the average person would not see as a key hole. Would love to see more.
#36 - is just a cool logo. No chance in winning because it does not speak any meaning. Just looked great so I game it a rank.
Thanks. Keep up the great work
