Attached Link: Justine 1

The floor Justine is standing on is made of one primitive plane. Used a deformer to bend it so the corner is 'soft'.

Used again the big 1/4 sphere as meshlight but also added a second meshlight made of a half sphere. Reality luckily gives the chance to 'invers direction' so the light is emmited from the inside of the spheres.

The render ran for 3 hours and 33 minutes at 75 S/p. 

Also added the scene set-up so you can get an idea of the size of the meshlights.

Hope you like it.
