Re-spray photoshop bike template?

I had my bike resprayed in armourtex. They have a very poor choice of samples. Before heading there with a frame i took photo of the bike and put different colours from the ral palette they are using. After respraying it looked the same as my photoshop picture, so it's a good way to find out how it's gonna look in reality. Dont use template - use the photo of your bike.

a good tip, but i also need a way of specifying detailing/decals on a flat image.
