The song really portrays the heartbreak of the character, and the murky, unforgiving sea which he has committed to. You can almost see and hear the ocean, and feel the main character as he reflects upon what he's become and what he's lost. The instrumentation is spot on. Like any good post-metal group, every instrument has its say, and everything's beautifully balanced.
There's movement in the song where the main character and his former lover exchange words, presumably over a distance, where the torment and pain of the situation is palpable. The song, and the album's concept in general, really hits my soft spot for stories of pain and failure, and the proverbial fall from grace. It also invokes great imagery.
