Really liked the ambience portrayed in your piece! Sound selection were great, (Especially love the pad at around 1 minute) but I think some stood out a bit too much against the underlying pieces. Such as the section starting at 2:40, where the the idea is great but could blend in with the prior section in a cleaner way. You set up a lovely space with the introduction of the synth at 2:24 and its little additions until 2:40 but the bell sound that comes in there seems a bit too distinct from the rest of it and felt a bit jarring.
Each section is distinct with its own melody and vibe and serves to offer a point in the journey but would be great to hear a bit more about what they represent, and somewhat hard to link that back to the original prompt sometimes as it seems to be more focused on the lighthouse instead of the far reaches theme.
All in all, great work with some minor nit picks, and would love to hear more!
