Graffiti Photography

Hi!
A couple of years or so ago, I completed this series of photographs incorporating figures against some remarkable graffiti art in downtown Toronto. The project is called "Alleys of Hope". These images were made late at night and I used a flash light to paint areas of the scene. I also used extensive photoshop post processing techniques to bring out color saturation and detail.
The entire series can be viewed on my site at: www.carminegroe.com

I am curious what you think about the images and if you're interested in this technique?
Cheers, Carmine
