Flying Boat [Stylized]

At the beginning, I imagined a boat pulling other boats behind him but I slowly go on an other way and made this flying ship wich is a sort of " flying house ". I don't really know what i did but i like it.
But i know i made this project in order to improve my workflow with blender and with Non-photorealistic rendering.
Also that's why I only used a diffuse-map for texturing.
