Toying with Texture

I stole a few moments yesterday to take a brisk walk near the Narrow River and take some photographs. I'm not really thrilled with any of them - I was rushing and didn't have time to drive to all of the different places I wanted to go. I did get some good texture shots, so I used the images to play around with overlaying textures some more. I've done a lot of brush texture overlays in the past, and I've done digital sandwiching of images - now I'm trying to sort of combine the two ideas.
