Wow, big difference between with the window closed and open. If opening the window is not an option, at least compensate for it by creating the correct exposure contrast in post processing. How I would do that with this photo is by setting the black and white points, usually with the Black and White sliders in Lightroom, keeping my eye on the histogram. Maybe I can show you on the webinar tonight? https://www.lenspiration.com/webinar/photo-critique-48/
