The picture is not very bright as far as lighting is concerned. She looks like she's in a room where the lights are off, but the sunlight still comes through the window with closed blinds; it's during the afternoon. Her facial expression, to me is paused, as though waiting for you to say something.
It's like you made this picture in remembrance of someone that was dear to you. At least it has that feel to it. Where is this character from?
