Nysuatro: There's not really much to show man. Same methods apply for creating textures as I showed in my tutorial. Just lots of layers and color tweaks. Sometimes I look at textures that has been created for next gen games (games that support bump, spec and etc.) Then try and recreate them using photo reference from CGTextures.com. For example that metal floor texture, I was inspired by some of HL2 textures. Tried to create something similar.
The best way to learn and become proficient at something is to study masters. So look at the textures from your favorite game and try to recreate them. You WILL learn a lot from that. I did the same thing with level design. I would spend lots of time analyzing levels from my favorite games.
I just realized that I make big mistake by not saving the .psd files. I usually flatten the layers and make sure they're tilable. Thus overwriting the layer stack. Otherwise I would have lots of .psd files to show as an example. I'll make sure to save .psd in the future.
