Interesting concept, and well thought out. Wondering if the light sources could have been brought closer to the book and garbo to sharpen the edges? Still, its a nice photo and good job keeping the exposure right without too dark shadows or blownlights.
Interesting play of light and shadow. Very neat idea indeed. However, the composition of your photo could use some improvement. Either rotate the book so it is diagonal and more interesting, or center it and show both pages equally as an open book symbolism. Simple black background you are using is good. You were probably trying to focus on the angels, so the forefront of your photo is a bit blurry and distracts from the rest of the photo. Not a bad photo.
I'm glad not everyone took this so literally. Let me ask you a question. If you were talking to a stranger that didn't know about the bible and you didn't have one to show them, how would you describe it? Not just physically describe it, but what it means to you. That is what you should have photographed. I see the light/dark spots, but they have no meaning.
