Download the brush and save it to your documents and then in photoshop in the brushes palette click the blue arrow in the top right corner and select load brushes and then browse to find the brush you downloaded. When you have finished with the brushes click the arrow again and select Reset Brushes because it will make photoshop lag starting up with all the brushes loaded.
Check the resources thread in Graphics Showroom there should be some font links there.
Nothing wrong with it...but it needs more. The design is nifty, but expand on it with other stuff. Overlay other patterns infront (with a fade perhaps) or behind it. (To bring out the one you've got a little more detailed.) Minor things like that go a long way. Especialy with bigger gfx/less cuts in the picture.
