What a loveley ambience you've created. It has a bittersweet sound to it that really gets that romantic and longing tone.
Only gipe I might have is the presentation of production. By itself it sounds quite loveley but I feel like it is a bit drowned in reverb or missing somewhat its presence to really get the presentation quite right. It always feels a bit like it took a step away from the listener and never like it envelopes me and get me into the scene. Which could be an effect you've wanted to create a feeling of reminiscenes and that the character is thinking about the past.
