After a couple tweaks on the image, I had in our sketch thread, I decided to go ahead and give it it's own thread.
It's Erengi's with Sennelier's white (my Erengi whites are all used up), on "Yes" watermedia canvas (it's a portrait weave and it's ground has a lot of built in tooth), 11 by 14 inches.
I know the piece has a number of issues, the figure is backlit but my attempts to darken the dark side of the figure just didn't look right so I'll pretend that there is a 30 storied, mirror faced hotel, behind the viewer, reflecting light back to her darkside.
I'm going to leave the piece as is and perhaps someone at an art fair someday will like it enough to take if off my hands.
The reference photo is from Tatiana's OP Challegne of a year or so ago.
