Thank you for those 3 proposals, we find the idea to split "expo" and "naute" interesting. We think that the font is a little bit too common, and the colour too drab, there could also be more energy. Furthemore, your work on the "x" looks like logos of French an Belgian bank and insurance companies : Axa and Dexia. This is the reason why we chose #5 first.
Thanks for your new proposals. We are not really keen on your new fonts (too sporty for our target audience), and we don't see the strong idea that we are looking for. Perhaps you can try something different, closer to the art world.
