Thanks for sharing the video, these kind of pictures seem to do take lot of work- but your result is well worth the toil. It's great you share this eye-candy with us.
By the way, I only now saw the larger picture (forgot to click it earlier) and it's funny how there her smile doesn't seem bitter at all, but full of life and challenge and even contempt, as if she's ready to spit on your face any minute, should you give her slightest reason to do so. And there is even more amazing little scars on her skin and other details like that! Wow!
I've now babbled a lot about what feelings etc. this portrait evoked in me- it would be far more interesting to know what you thought while doing it? Any particular things you were aiming for?
