The Dark Office

I took this on at a TV studio I go to sometimes. Like many places in India, we get a lot of power cuts, and this day was no exception. I was at the far side of the office, facing the door, and the woman is the photo was on her phone, casting a faint light on her face. I only had my mobile phone at the time, so I didn't get the photo I was trying to get. But this one turned out pretty good too. And after a bit (not much) of work in photo shop, it looked a bit better.

Update: I know the quality is pretty bad, I was trying to get as much detail on the face as possible. But I just got a whole lot of grain. Any hints?
