This is an interesting piece as it draws attention to the girl and then the umbrella. The collections of items behind her provides great background detail and adds to this photo. There is a story behind this work and the audience would like to know more.
I would suggest that the light coming down from the umbrella be evenly dispersed/less directly angled in the room as it seems more natural/magical for light to act in that way. You may want to consider cropping the door frame as it could be considered distracting.
You manipulation technique makes the story come alive and makes the audience question why she is sitting there. You did a great job.
