I really like all of your logos actually.. I still keep going back to the ones with the narrower tree, Here is a comparison of #13 and #27, I wonder if there is a way to merge them:
I REALLY like:
The human form coming from the plant (which is coming from the ground) in #27 and the simple colours and colour coordination.
Also, the ground under the word "ground" in #13 and the word nutrition on the right.
I'm NOT as crazy about:
The bulkiness of the image in #27. If somehow the leaves could be a little narrower or more streamline..
I feel like you were on to something in #14, trying to incorporate the human form growing from the ground. I'm just not too crazy about the polka dots...
Ack. I'm sorry to be so difficult. I'm just having a tough time deciding between all of them. I thought maybe if I could combine my favorite aspects of all of them, we could have a winner! :-)
