What I was trying to do

I spotted the subject in the window reflection of a train as i was heading out of Berlin back to the airport. She seemed quite melancholy, but had a striking look.

What worked

I like how the subject is mirrored by the other person in the foreground just out of frame and how her reflection frames the main subject along with the leading lines of the train tracks.

What I'd do differently

I have a landscape version of this photo showing more of the person in the foreground which I think compositionally is better but the main subject is looking down so it doesnt show her eyes. I felt this was more striking so I went with this version but I like both!
