This is absolutely brilliant. I am quite impressed. I would say that I wish the picture would extend the entire way -- I rather dislike how it fades out toward the edges as the fade is inconsistent. I also dislike the fade because the quote in the bottom left corner then fades back in and that seems odd to me. I also think the lines leading from the bubbles to the map are too thick, but that's nit-picky and a personal opinion.
Beyond that, I love it. You have a great color scheme here that really fits the feeling well. This really is a great piece.
