Distressed Water Tower

I decided to take a picture of a water tower not too far from my house and give it that 'Walking Dead' feel. In Photoshop I used some textures of scratched metal and blended it with some other coloring. I created some rust brushes and fitted them to the tower using the warp tool. I added some graffiti, vines and busted cars to give it an abandoned apocalyptic look. Then I used the color lookup tool to finish it off.
