If you use Photoshop CC - you can also use Adobe Capture App for mobile. This app allows you to make many different textures from real word. Maybe try this?
Your work looks beautiful.
If you might like to work with brushes, instead of found images, you might try something like brusheezy.com
A quick search for "interior" gives me some wood, stone, brick, and marble results.
thanks for the replies. so there really isnt a web based service that has materials categorized for easy viewing/selection/download? we use autocad and there are hundreds of web services like that. i figured photoshop would have that also. If anyone else has suggestions it would be appreciated, i will continue doing the standard google search. thank you!
This is not really an answer, but have a look at SketchUp. The free version comes with a ton of useful surface textures, and with additional, all free, plugins, you can do photorealistice renders. It's easy to use, and there a lot of video tutorials for it.
Not all the render plugins are free. This used Vray which cost serious money ($750) but Visualizer is as good as free. BTW Most of the contents of this room would have been downloaded from the 3D warehouse, and it's all free.
