It's a good job :-) The back travelling works, and the black areas are well done. It makes me think a little bit of Hellboy. You're right to keep it in black and white, your drawing don't need colors to be understandable. Or perhaps just something very simple, like flat colors.
I just have a little observation : in the last box (don't know if it's the right word :-) ), the left side is black because there is lot of shadows. I think you should continue the black on the right and in the bottom, like around the other boxes. I have no problems with images that take the full page, but in this case it's a bit strange because of the shadow on the left...
I'm curious to see the people on page 2 :-)
