I like the pads at the beginning. They have a warm, bright vibe, yet seem to be slightly detuned or distorted in some way. The snare is really wide and full-sounding, yet not too heavy. Nailed the mood and atmosphere here. It has a good sense of direction by around the 2-minute mark, but overall there isn't much in the way of distinct structuring here. I also think you overuse the swelling white noise sounds during transitional moments. The groovy bass at 3:07 accompanied by the bouncy piano (as well as the melodies at 3:28) constituted my favorite part of the song. It finally feels like I stepped off the train and into the open air at that point. That said, I did like the thematic elements of the piece, including the train announcer vocals. The fade-out at the end seemed a bit lazy to me, but I suppose this piece is supposed to be about an ongoing period of bliss anyway. Overall great work! This is the sort of track that's really easy to get into. :)
