Excelent blending, and composition! The model's blond hair works very well with the foreground (right frame) Zone 8/9 and the background's bare blac of zone 1. Nice work!
The narrowness feels awkward to me. Excellent lighting on the model. Would also be nice to have the foreground window frame in focus it's blurred enough to be a distraction as bright as it is.
Too bad spot editing is not allowed here, because right side of the frame could use a little "burning in" to add some tone to the large white area. Good work.
