nous sommes humains

I like how the image provides a sense of rush, of movement. As you said, it even feels like something wild is being captured. From a composition standpoint, I wouldn't dare to critique it; however, from a street photography angle (and a true fan of it) I think the movement would be better represented if only one object reflected it. Either static train and blurred passersby, or static people and thw train on the move. This slight change would make the whole photo feel anchored, or rather make the viewer feel drawn to its flow of stability vs movement.
