Exquisite lighting and posing! I instantly liked this scene. I hope you don;t mind, but I saw a couple things I wanted to see altered, so I pulled the Original size into Lightroom and did two things. First, I cloned out that tiny,tiny spot on the edge of the window frame. Then, I cropped off a small amount on the left side of the frame, to focus a bit more attention on her line of gaze, and a tiny bit less on the veil. I also very subtly lightened the shot, to emphasize the beautiful,subtle highlights you captured. While I absolutely love the original lighting and pose, I wish there were a tiny bit more space above her head. Still, I LOVE, just LOVE, the subtlety, and the beautiful true profile pose she is in!
Here is my quick rework. I really,really think the lighting you captured is superb.
I actually think that by cropping off the extra bit of black to the left of the frame, that it adds a bit of emphasis to the veil, while at the same time, really strengthening the out-the-window gaze. This photo is well worthy of the name "study".
The reason I cropped that way was to remove the daylight, bright area. While that helps to tell the story of looking out the window, I chose to eliminate it to keep the eye from being drawn away from the subject.. (within the guideline, that the eye is drawn to the brightest portion of the image). Probably overkill since it is not that bright, really.
As requested... Binga, I hope you don't mind... lol! A different crop with all of right side of image included.
I like what Cgipson did, I found the dot and the bits of light on the curtain a bit distracting but i would also get rid of the hair on the neck level. These are little details...
Otherwise this is an excellent shot, I love the vintage feeling about it of it and the lighting.
