Here's a thought - as I read this thread, and your comments, Andres, it struck me that it wasn't terribly obvious what kind of critique you were looking for (this is the User Critiques forum after all... What would have helped me was a statement at the top setting your expectations - ie, How do these images strike you? or something like that.
Otherwise, its left to the user as to figure out what you're asking for, and given the nature of the forum, we'd assume you are looking for a critique of your images. The images are great - so I wouldn't expect a lot of comment, as improvements to the images are perhaps hard to imagine.
My reaction was that your images are powerful and evocative, and you tell the story well. Not being very strong in photojournalism, at this point, I can't really add much in terms of how I think you can improve. The last couple images are perhaps a bit heavy and flat in terms of tonality, but that may very well be intentional.
