Create a new layer above the bodice now (Layer - New Layer). Picture some ornaments on it by choosing the Brush Tool with a star shape.

 




Applying the usual Brush Tool and the Smudge Tool, the skirt will look more voluminous. Select the Dodge Tool after that to decolorize the lightest places on the dress.



Apply the filter too: Filter - Brush Strokes - Accented Edges.

 

Make a copy of the ornaments' layer and blur it out (Filter - Blur - Gaussian Blur) 7, 5 px, just to give the ornament a luminescent effect. As we can see, the band on the girl's head is not necessary, that's why it must be deleted with the Eraser Tool. After that, select again the Brush Tool and the Smudge Tool to represent the skin on the band's place.



Make the skin look lighter on those places that are a little darker. Use for this the Sponge Tool with the Mode Saturate. Now we should smooth out the transitions between the colors with the Smudge Tool.

 



I decided that the sleeves should be erased too, applying the same method we used in the band's case.



Erase now the layer containing the contours. On a new layer above the skin's one, we should represent the girl's hair. Use for this the Brush Tool. Create the background's layer also, lower than all the layers. Paint it in a grey color with the Paint Bucket Tool.



Further we need to apply the Brush Tool and the Eraser Tool to represent the hair.



Choose the Burn Tool and the Dodge Tool to deepen the shadow and accentuate the light.



Choose after that the Smudge Tool and smooth out the hair's locks.



Set now the next adjustments that you can see in the table for the Brush Tool.



Introduce several other nuances on the girl's hair with smooth lines of medium thickness.



Blur out the lines again and it's not necessary to do it extremely accurate.
