I love the use of the fractal as well as her pose, you don't always have to see the face to get a feel for emotion..  As you mentioned some of the black on the sheet, I might also use a smudge tool to smooth the area below where you'll do the touch up for the break through... Just a  little can go a long way in adding a soft and gentle feel to the sheet...

Great image, I'd love to see if after you do the postwork...
