For #7 it is the letter "A" which looks like a leaf. The arrow represents upward growth and "renewable." I'll see what else i can come up with. Thanks for all the feedback.
#60 like it a lot. Thanks. Like your ideas in general. Going in another direction altogether can we try a typical adobe building block at the top? I have this idea in my mind and would like to see how it looks. If it is too much to ask, no problem! Thought I would put it out there...
