I usually don't care for ambient focused songs, but even something simple as those bells just doing a triad were enough for me to pay enough attention. Especially because you later developed it into a real melody as the song progressed.
Stuff like those distant background bells that came and went, the guitar, this at 1:58 and 2:28 all helped the track stay interesting without losing any of it's ambience
While a mostly liked the melody (loved that chord happening at 1:14), some parts near the end felt a little too "aimless" like at 2:16 (alone it sounds perfectly fine, but within the song it sounds a little out of place, like, I felt that the part around 1:46 was the climax ending down at 1:59, so to introduced a new less climatic climax after that wasn't called for)
