#65 and #66 are great. I like all of the elements in them. Is it possible to work on a symbol similar to what you've got, but less obvious that it is a leaf? Maybe try a couple new symbols like them, but more abstract. Good start!
Thank you for trying additional variations on the first two you did. Unfortunately, I prefer the symbols in #65 and #66 better than the new ones #83, #84, #85. I would still like to see the symbol without the leaf being so obvious.
For #82, I like that you tried something new, but I don't think the white letters on color background is a good look for us.
I like the symbol in #118 and #65. Can you try a couple of different fonts/typefaces for TOPO? I like the one you are using, but my partners are concerned it might be too futuristic looking. Some other good references are #59, #144, #141.
Another request from my partner: Would like to see the designer play with the logo a little in #118. I'd like to see yellow instead of black, maybe even a version with yellow EXPLODING from the center of the green ball.
