Her secret

Finally, it's done. It was differ for me to draw so many dark places, almost black. I try to create the mysterious atmosphere in this drawing, hope that I could. Of course it's not ideal, but I like it.
For the reference I used wonderful photo [link] from the 'gallery. Please take a look at her others works, she's great.)))

I used:
- regular and mechanical graphite pencils, graphite sticks;
- kneadable eraser, pencil-eraser;
- q-tips, blending sticks, tissue;
- Munken paper - album for painters 160 g/m2 A4.

Time: ~15 hours.
Size: A4.
