With regard to the three wallpapers used in this work are images taken from a pack called ''76 Wallpapers Cities'' downloaded some time ago from the internet, who are not the original authors nor the web page where download. Although if you helps, I think in the wallpaper Saint-Petersburg, New York (girl legs) and Manhattan Bridge appear. Everything else is of my own making. The model used is no model or actress or anything, it's just a friend of mine.''Si quieren ser primeros, no compitan contra nosotros.''
