Texturizing

I recently started messing around with adding texture to pictures.  I think it adds a fun aspect to the image.  Obviously, I wouldn't do it to all of my pictures, but they are pretty cool looking.  Here are some different examples of images before the texture was added and after.  I'd love to know what you think!

 This one is probably my favorite, because the wall looks really cool.

 This one has a design rather than just texture.

 This one is a bit more subtle.
