I'm mot sure how I feel about your project. From a visual perspective, I find it interesting and appealing. However, I'm not happy about the use of the abandoned and tagged sites.

It might be OK on the interior of abandoned buildings, but when it goes outdoors on public property, then it bothers me.

For example, the doorway of the abandoned building....I hate to see further destruction of the property, not to mention that there is now paint on the sidewalk. Although you might see it as artistic expression, I think it invites more tagging and destruction by others.
