Where do you find the perfect textures you use in your artworks? Is there a site? I can’t find nothing!!
check Blendernation, they just submitted an article on texturearchive.com, and if you read carefully the comments, you’ll discover much more great sites sharing textures… 
Uh, but keep in mind that there are no perfect textures. Most of them require a lot of work in a 2d image processing programe like Photoshop to be mixed with other textures or to be enriched with details…texturing is quite some hard work, actually. Don’t ever expect to find something perfect already premade, you need to adjust it to your own needs yourself!
thank you!!!
Take your own texture photos. It’s way better IMO (that is, unless you can’t get them for something i.e., a road from birds eye view).
