I really see the image differently then. To me it looks like the person is standing in front of a kind of wall (depth-wise) and the left and right sides of the image come closer to you. Thus, the "wall" (the colors close to the person) and the render itself should have the same sharpness because they've got the same distance from you.
I'll try to show it to you
Maffe however sharpened the things I would've blurred and blurred the things I would've sharpened.
So to me it is <wall>, <girl>, <things left/right fly towards you>
