Many times the reflection is good, but I think in this case, it's working to your disadvantage. The scene in the background seems so charming, and yet we can't see it very well. Seeing the reflection of the mirror seems to dilute the power of her isolation, though in some ways I can still justify it. Would recommend using a circular polarizer to reduce the reflection, if that is your desire.
I like it. For me, it's the beautiful landscape outside the window that makes this shot. It looks like a great destination. I like the look on the woman's face as well. Good luck in this challenge. 8
