Its photos like this that i love. Your mothers contemplation, the way you framed the picture, and the things in the room says so much about what kind of person she is. She seems like a thoughtful and awesome mom.
One doesn't need an electric solarium over there, what a relaxing environment, nicely captured in soft light and tones. Good that you took the whole of the window in the photo. Although I'm somebody unknown to her (and she to me) please give my best wishes and regards to your mother!
