Which object is casting the light? Is it one outside the composition? That's a terminological nitpick, so ignore as you see fit. Lovely figure (yours and hers, sorry about the pun). Back to my nitpick/praise; I'm not sure that is is correctly called Osl, but whatever it is you appear to have nailed it. Marvellous effect, she appears to be under UV light, which A: looks spectacular and B: seems appropriate for a Commoragh girl.
