The updates are strong. I like the font, kerning, leading and position. That's why we ranked you number 1.
The tree logo is strong but feels more like a nature conservancy than a historic homes conservancy. What would be great is if you could find (or produce) some kind of vector drawing of a Spanish Revival home. Those types of homes are the pride of the neighborhood and would work well as the logo.
I'm going to post some photos of these homes, but if you just Google "Spanish Revival homes" or "Spanish Colonial Homes" you'll get some ideas. Perhaps we can focus in on a section of the home, like an arched window or something, and show the overhang of an adobe roof.
What I like about the tree logo is that it has a beginning an end. Doesn't feel like it's missing something. If we were a parks conservancy, it would be perfect. While parks, nature, etc are part of the mission, it's not the main drive.
Hope that helps.
