Nice, you chose the same art as I did last year :D
"Departure" has some Starwars vibes, which is not an easy feat to pull off. I like the use of runs and the orchestration in general. The loud cymbals make the track sound very open.
The transition to "In the Storm" is smooth. I really like the use of trills in this section.
In "Clear Waters", I think the arrangement could use some work. The choir sounds a bit awkward carrying the melody because it lacks definition, and the glockenspiel also feels inadequate for this task as it lacks sustain and a strong pitch. I notice an absence of bass frequencies in this section, which diminishes its impact.
"Seafight" reminds me of "He's a Pirate". I like the huge percussion here. I still feel a lack of bass, which reduces the power of what seems to be the song's climax? The percussion seems like it's above the melodic instruments frequency-wise. Although the loud percussion is nice, I would also like the melody to be the main focus. And speaking of melodies, the melodies in this section kinda feel like placeholders to me. You clearly achieved your goal of depicting a sea fight, but I think more could be done to make the section memorable and striking.
"Farewell" doesn't evoke much emotion for me. The chord progression feels one that would be used in ambient music. I do like the instrumentation and the contrast in this area though.
This was an ambitious challenge and your composition lives up to the section titles for the most part. I enjoyed listening to it and look forward to hearing more from you. This review might seem more negative relative to my other AIM reviews, but that's mainly because I'm much more familiar with your style of music so I naturally have more to say.
