There is a Camera, Sun and 3 Models in the scene. All materials and textures are name so its easier to navigate. Very easy to Render, everything is finished you just need to press Render button. All Textures are packed with the .blend file so you don't need to search for the textures and assign them to Materials again when you Download the files. The Textures folder is included if you need to change anything. No need for any other plugins everything was made using only Blender original tools. Clouds also have shadows under them for an even more reaistic effect.
