Creature Design Test

This little guy is the first finished result of a design process i started for an own project. The basic goal is to design creatures that are living a wide open aerial space, large .. the size of wale and bigger. I want them to be shaped and designed after the bodies of nautical creatures (because i like the idea to see them "swim" and glide through the air) , thats why i made all the fish sketches at the start . You can see them on the last picture. Also i wanted to modify the nautical to make it look more aerial and maybe ad some dragon features ...just because .. they are .. big ..and living in the sky. Also i thought about the food chain, added an element that they get from their food and deposit in special organs where it reacts with body - electricity and a special segregation and starts to negate the gravity . Unfortunately i missed the goal on this fist attempt ... but i made a cool fish i guess ;)
