Of course being "out of place" it's important to show the surrounding, but I think you did it just right. I also enjoyed looking at the other images. I would have been in heaven there with my camera too!
I love grafitti and have a big collection of photo images. This is a terrific photograph. I like that the hard structures and the graphics are framed by the soft greens and browns of the surroundings. I am going to check out your other grafitti photographs.
Since I'm in Whistler for a while I decided to go to one of my favourite spots on a trail named "Train Wreck". About five or six freight cars derailed here about 50+ years ago. The forest has grown around them and now it is a favourite spot for bike rides (who jump off the top of the cars) and graffiti artistes.
