The truth is, and I don't want to be rude, but in my mind a romantic picture should have a beautiful young subject. If a picture is too be beautiful shouldn't the subject of the picture allso be beautiful??
I don't know; it sort of looks more as though she's trying to salvage a sweater that's flying out the window. Maybe if a bit more of the "hair" were in the shot, and woman wore a more "longing" (rather than shocked) expression.
Nice idea. Focus on face would be better as well as less motion blur. Try cranking up the ISO. Also cropping out some of the shutter and a little of the out-of-focus bedsheet rope would be better.
Not really ure why I struggle with this shot. I will be interested to read other comments after the challenge. I think it's the composition and the movement. Sorry I can't be more helpful.
