Yes i know.. they are a way tooooo large. But i don´t want you to use them.. they show how to create the colormap of a planet surface. Mat colors for water and Ground textures for landmass. The depth comes from a second skin (the bumpmap). That will look like that: http://www.imagesload.net/img/Earth.jpg
Your texture looks to bright with to intense colors. And the clouds look like a kid had fun with Photoshop brushes ^^"
