We like #65 a lot. We need to be sure it can work both on a white and a dark green background- can you develop it a bit more and also show it on both backgrounds?
#81 looks very strong. Can you work in a thin underline below the name? Also, I think we will stick with the green/white palette. The blue jumps out a bit too much after all.
My advice to you, trust in my experience. innovation in all areas of design and the designer a clear winner. From the beginning of the competition, especially in the sample not used in our tree. very important for me to make a difference, did not want to be easy.
