I must say that I am new to the entire cartography scene (this is my first post), and stumbling upon this topic was a blessing. Your work is phenomenal, even if you are just taking textures and turning them into objects. I can't quite afford Photoshop yet, but plan on getting it in the future, but have been using GIMP for the time being. Any pointers for a newcomer?

As for the EULA question Redrobes asked about, the cgTextures.com site has a section under About concerning the licensing. As I was reading the licensing info, it seems that you can use the textures for personal and commercial use, except that you cannot resell the textures as is; they must be modified to fit a model and cannot be sold as a texture pack.
