I enjoyed the arrangement of the orchestral elements. Mix wise, things kind of felt flat/static to me; more attention could have been given to harmonic movement, velocity and making use of space. I'd recommend adding some reverb to make the orchestral sounds blend more and more believable, some compression/side chain compression to let the drums punch through; using "ear candy" like risers and impacts could highlight particular moments and overall theme wise to me I felt more of a desert kind of vibe with percussion than a aquatic or "sea" vibe at parts. Well done otherwise!
