Based on the entries so far, I like your work the best, so hopefully one of your designs will be the one I go with.
Do you think we could make the color for the 'G' a bit more green and take out some of the yellow. I don't want it to necessarily be darker, but if there's any way to give me another take on that color that would be helpful.
Also, I really do like the simplicity of the logo, however, if you think there are a few minor details you can add around the 'G' I would be interested in seeing your creativity there. Perhaps there will be something I like - as you can see with The Herjavec Group logo - it keys in around the letter 'H', yet still has a bit more to it. Hate to sound picky, but would love to see if you have any additional ideas - love your work so far.
As I commented in the tournament, I would be interested to see if we can add some character and detail with some type of leaf or green element/design that shows our buildings are also going to run efficiently with a sustainable/environmental focus when possible. This would look great with the green as well obviously.
