Enjoying the vibes and feel here!
I have seen some comments about how the melodies maybe feel a little aimless and, while there's some truth to that, I also think that it does work for the out on the ocean scene you wanted to go for with this. It has an endless wavey kind of feel and I appreciated that. I also enjoyed the business of the tracks for that reason as well.
I do agree that there is a flatness to the production and the way the instruments are playing. I think more use of dynamics in each instrument would go a long way. Maybe some other instruments too. And I do think it would help to have the songs evolve and change a bit more throughout or yo just have some other tracks with different tones and feels, but I still very much enjoyed what you got down.
Also, I love the story idea you have and how well it fits the theme! Some other tracks that put forth some different feels would really help tell that story, I think. Nice work though!
