As to the first photo, which technically is a) too dark, indeed, and b) showing signs of camera shake in the lights of the background, I still believe that it has something that goes beyond these technical flaws. There is a compositional element to it that I see and feel and like. It is the woman - who I clearly recognise as your subject! -, her gaze and the way she holds her arms. All these elements create a sort of triangle out of the lower right and opening up into the top left, where the other person, very dark (unfortunately) stands and forms the "recipient" of said triangle. (If something like that can be said at all?)
I am bugged by the rubbish in the corner behind the girl (starting with the SPAR-bag and lots more there is) and on the door, it is quite distracting, indeed, but her gaze and position are compelling!
