To bad about the backdrop...
I guess this is a self portrait and NOT your girlfriend :)
Like the photo, like the backside too, nothing wrong with it. Don't forget to iron your sheet next time before using it as a backdrop, and watch out with those shadows... (8)
Wrinkles in the sheet in the background are annoying. Nice setup of composition and lighting. I think the title could be better constructed, but it is better then some in this challenge.
Good idea, but the shadow that the girl is giving off, draws the eye away from the subject. Maybe get another light source and shine it the other way to minimize or take away that shadow?
The cloth seems too wrinkled and she's too close to it that it becomes part of the image instead of being the background. You may want to try her being further away from it and have some lights aimed at the cloth to brighten it so it becomes more of a solid white background.
I really like the shot your model, I don’t care for the shadow or the backdrop....maybe if the model was a little further away from the backdrop it would help
I bet you didn't tell her what the title was... I like it (and the photo). Possibly a bit of ironing might help the sheet though, or put it further in the backround and make it out of focus with a large f.
