When I saw this photo, I immediately thought of the word “Dark”:
This is an x-ray photo of a cargo truck filled with human beings. So many thoughts, emotions and feelings went through my mind. I could only imagine the darkness of their situation.

Wow, your dark picture is painfully beautiful. It does potray the darkness of illegal immigrants. Lovely work. Well presented.
