Ocean Bridge Trawlers Final

First time using blender. Design is based on a screensaver image I found online. Used the CG Cookie tutorials to learn the different methods to eventually achieve this final design. All the models are created by myself. The textures also my own work. Found the Shaders Node tutorial very useful especially with the ocean. I do recommend watching even although some parts very in depth. The background is an image plane that I altered in photo-shop slightly. Used one of the default skies for the lighting. I wanted to keep the image darker but felt I was losing some of the detail. Comments welcome.
