We like the graphic a lot, but we're not crazy about the word mark. Could you try it with a different font? Maybe something a little heavier, a little more organic. Not too much, though.
Also, we like the colors to be a little more pure. Your brown looks a little too orange. And your green and blue are a little faded. Can you make the brown a little more rich (like chocolate) and the blue and green brighter? If you do these things, it will get a stronger vote from some of the people on my team.
Thanks for making some changes, but we still think your colors are too dull. We like your concept for the mark, but without some sharper colors we think your design will be eliminated. Please consider a richer brown and blues and greens that are not faded. Also, try staying with a black and/or grey word in all lower case. That appeals to us the most. Thank you.
