I would say A for effort
I like that your thinking outside the box, creating a clean background and using the headphones to breakup the image, and utilizing the window lighting to make light with creating highlights on the face.
While I realize you where working with what you had on a rainy day, this is what I would try for a re-shoot, the toilets a little odd (unless that was your intention, but doesnt seem that way) and the picture behind your head catches your eyes first, not the face.
If your going for a clean background your going to have to find a new background...Take a walk around the city and look for some cool backgrounds, keeping lighting in mind.
One thing that comes to mind, an alley in between two brick buildings, the can bounce some very warmish light that looks great. Sit down against one of the walls and set up your headphones like you did with this photo, you might want to bring them up some too, even better try the rule of thirds for placing the headphones and you face. Try to find a spot that will light one side of you face brighter than the other, just like you where doing above. Depending on the alley and your lens you may need to have the camera like 45deg to you instead of straight on. If you where on an angle like that you could also try and open up your aperture to blur the bricks away from you
anyway i'll stop rambling but hopefully it got you thinking up some ideas
