I loved the background start to finish, myself.The papers on the foreground make a nice mix-up with the clouds behind, almost like they're a pair of frontiers separated by the border of the window and if it was removed they could even come together as one.The way they spiral and tower above makes the character seem imposing even though she's smiling so serene.I also like how her dress spirals and flows along with the papers. Considering the windows are closed, this is maybe hard to notice but an added supernatural feel in itself: There's no way there can be wind blowing inside in this case if not by the work of something above humans, isn't that the case?
