There are clipping issues in the latter part of this. And I don't think I heard a clarinet...unless it was playing in the same range as the bassoon, which could be the case, since I misread 'quartet' for 'quintet' (I wrote a woodwind quintet these past two-three months).
Other than that, I liked the arrangement. It portrayed the Great Sea as a calmer, gentler place than the original song, though that could be the absence of a snare drum. Although for it to make it on to OCR, you'd probably have to be a bit more liberal with the theme, really giving it your own flair as opposed to directly transcribing it for four instruments.
