For this type of formal collage to work I think you would need to flatten the bills. Maybe iron them or something. I'm too distracted by the not quite straight lines and almost symetrical layout.
I think by far this is one of the best pictures and titles of the Challenge. I really would have like to see it portrayed on a different background. But a awesome idea and picture non the less.
Nothing in focus and I'm having a hard time relating In God We Trust as last words and tieing it to the overall picture. Also, the green scaley background is very ummmm clashy.
How do these bills relate to the words, other than that they appear on the money? And how are those words "last" words in some sense? Maybe your notes will help explain it? Sometimes context provided by comments makes all the difference in the world, but DPC focuses on purely the image and title.
Aside from that, the shot is dimly lit with low contrast.
Okay concept, but photo itself is kinda dull. Try working on the lighting to bring out more details in the currency. And the green background is very distracting.
