Let's go with #338.
Please shrink the emblem a tiny bit. Please give just a little bit more space between the emblem and the wording. Please try giving the slogan just a little "bold" (same typography, just thicker lines).
After doing the above, let's look at a version without the leaf detail on the "e". We are getting mixed reaction when we ask potential customers. When it is big, it looks great! But, when it is small (business cards, product labels), it is hard to see the detail and it unfortunately looks like the "e" is just misprinted. I love the idea.
What are the final details for the contest? Are you able to possibly give us a couple of versions of the final logo? It would be great to have the "e" leaf version for posters and large print and then a normal "e" for small print. It would also be nice to get the black & white version of the final emblem for an ink stamp pad to put out logo on shopping bags and the such.
