To go by the shadow, try a spot with a pretty high blur and a gold tint to the front and a little to the left.  And pointing down a little.  I'd point it at her head, and position the spot to get that strong shadow behind her and light her in the front.  Keep its intensity medium, and use IDL to keep the shading even.  To get the rim lighting, add another white spot down, to the left,  down, and behind the figure, .  I'd also point this light at the figure's head.  If you want a strong, thin rim, use a full intensity light and pull it as far back as you need.

If there's a Blinn node in the skin material, the Eccentricity is the value for the strength of the Fresnel effect on the Blinn.  More excentricity means rougher surface means stronger Fresnel.
