This is an interesting one. I know that she is on the roof observing other roofs but in a way she is also wearing a roof in the hood and cape.
An interesting thing that I learned from a tattoo artist a long time ago is that certain tattoos (especially in the case of traditional ones and sailors tattoos) have very distinct meaning. The interesting one that comes to mind from seeing this image is the umbrella. An umbrella is a temporary shelter, a temporary roof and tattoos of umbrellas traditionally mean that a person had been homeless or had lived on the street for a time.
Your image reminded me of that story.
