There was a couple of photos there that (in my opinion) could have done with being partly / or fully in color. For example the Japanese girl holding the "Horror in Japan" board. Make her in color with the rest of it B/W. Being new to this myself, I don't know if that would work or not.
Keep 'em coming, very nice shots. I'm going to add you on my flickr so I can see as soon as you add more..
