The monument feels a bit like a chess piece here. Also, we think it really needs to be white in order to evoke the Washington Monument. We think it is iconic enough (particularly to our DC-based audience) not to need such an architectural rendering (ground and side shadows, placement on a large plot).
We really like the feeling of your vine and your leaves, but feel that they need to be MUCH bigger. Outsized. In this design, it feels as though the landscape included is eclipsing the vine.
We had always pictured the text of the logo to be in a shade of green. Not fundamentally attached to that if it seems like it works with the design, but in this case the text feels a bit slapped on. Also the font feels a bit formal for our mission and operations.
