#13, like how you have used the mod style and made it look Caribbean! The text looks disjointed from the logo though, can you try combining the two parts more? Also, the look of beach balls and beach umbrellas in your Culebra logo is awesome! Can you attempt to do more with making the graphic piece look like something here...ie, sails, sun, waves, palms branches, etc?
Really like what you have done! We have extended an extra day and will extend more if needed, please let us know if that would help you with creating your strongest submittal.
