I like option 2 for the text and concept 2 for the design. Though the swirls kind of draw my eye away from the design. And they make it seem a bit unbalanced. Keeping the trees/hut, making the fish bigger and moving them to the left would balance it really well and get across your message. Really good stuff here. Can't wait to see it done.
