I enjoy #4 but the fact is the name of the company is greeno products right? well the o is lacking in number 4. I would suggest giving greeno a bigger lineweight and making products and the leaf the lighter color that you have on the o, I think doing that would make it pop very nicely.
Thanks again for all your replies. We decided to go with #4. I agree with the previous comment about the"o" lacking. The design company I hired through elance.com (Litmus) will provide me with different variations of that #4 design until I finalize my decision. Thanks again for all the wonderful replies.
6 is the best, i think its brandable quality. Just tone down the color of the "products", its shouting more than the green.
