A great composition
Obviously, you spent a good deal of time in this, and that is reflected in the quality of all the instruments and the mastering and such and such. Nothing is over-dominating, nothing is inaudible. I can pick ouch each instrument with ease, and I like that. Also like Cobra said, I can see ocean scenery, although that is hard to portray in music.
However, this is a great composition, and you should feel proud of it. Good job
