Thank you very much Debbie 
Here finally I got my work photographed.
This is the master copy I was working on, actually I had submitted this last Monday for critique. Known issues are short forehead and thin fingers. Any more suggestions welcome. Was done with only white charcoal on black canson paper. Original size 18"x24"

This is the drapery study we are doing. Black charcoal on medium gray canson paper. It’s still not done, shadows and some areas are still to be finished. Overall I am happy with this one.

And this is the current plaster cast rendering we are doing. I am king of not satisfied completely with this one. Something is wrong but I cant figure out, I kept editing it for a quite long time. But after those frustrating hours I realized that there is no point wasting time perfecting. Right now I have used only black charcoal on gray paper, but in the end I will add white charcoal as well.
