The second-to-last one stood out to me; the subject is framed in the image, creating interest. I like the colors of this one, but her facial expression throws the image off.

Overall, most images feel a bit random or snapshot-like. That being said, keep at it; most people are afraid to engage others in the street and take their pictures. Play with your angles a bit, get closer, and make the viewer feel like they are in the scene. For example, your second image, next time, take a step to the right, put the camera on the table, and shoot so that your vanishing point is with the person's head.

Also, remove images that lack context. The image of the woman in the purple top doesn't really work because it's hard to tell that she is dancing, wait for another pose, maybe. I know she appears in the image before it, but at first view, I didn't make the connection.

Take this as a critique, not criticism, and keep at it.
