Michael; In all honesty I'm trying but failing to figure this one out. The man is moving, so attracts attention, but seems unrelated to the balance of the image. I'm not capturing the significance of the suitcase on the conveyor, and the lift in the background is not engaged in anything. I'm sorry. Please help me get it.

I was trying to connect the single suitcase on the baggage return with the sole person in the frame - a commentary on loneliness, and perhaps an unsuccessful one.
