Like the concept but the design of the symbol reminds us a bit of the Episcopal church symbol. Also, maybe play with the colors for a bit more green, with blue as a minor color and only black accent. Nice idea, though. Like to see what else you have in mind.
Saw your portfolio...see what you can come up with along the lines of the Heather Hopkinson & Associates...the shield standing out is a nice touch...don't know how you can incorporate that feel into our requirements but interested to see what you come up with.
