The only like "negative" I have to really point out is, in my opinion, the music is audibly rushed.
But that doesn't really mean it is bad, like it's chiptune.
Chiptune goes either way, really depends on the listener.
But the motifs were used well, and in my personal opinion "#2 Shanty" could be used in a Monkey Island-like game.
That is if it's the same composition style but different sound design.
But good job.
