Hello Vince, I am also a newbie to CS and may be bit off track, but after taking a really quick look at the tute, I remembered something I found recently which is the wealth of brushes for Photoshop out there. Fantastic results can be had quickly by downloading and then loading grungy brushes. When you have the pic, just open a new layer, choose the brush you want to use (Open up the brushes pallete and click the right hand triangle and choose load brushes, point to where you saved the downloaded brushes) and then play around with a variety of colours and sizes until you find something that looks right. These finished pics can then be used for textures. Another way would be to take lots and lots of pics of interesting textures from real buildings and then tweak them. Like I said Im a newbie with CS and hope I wasnt too far off the point. Lupus55
