#80, #81 and #82 are looking good.
Keeping in mind this image will be used in all our marketing, including cars, uniforms etc it would be good to see the image in a more raw state. More sketch like rather than art like, the tree is the focal point, not the landscape. I don't think we need the birds.
The "picture" component of the logo seems to dominate the overall logo. Not sure if this is because of its size, or because of its "boldness". Perhaps if you have any ideas to address this it would be good.
Thanks
