Well done.
I enjoyed listening to this loop very much. I happen to enjoy these sailor themes myself, since there are not enough of these.
The only thing that I would change is adding a little pause at the end of the song because think about it. There is a slight pause in the song sometime near the end, and I believe it would suit the song.
I must say however, this was very well put. I expect more good work from you, my friend!
Good day.
