Love the light and the general look, but: she's out of scale. No window seat I know of makes people look so small. Especially the cushions. But I may be wwrong. I'd also crop the pic so the wall on the right disappears. That is, the dark grey flat area just draws the eye from the subject cause it's so different from the rest of the pic. And I'd add a bit more light to her face. Yeah, lower her a bit.
