3/5
The bass beat is a little annoying. Try making it lower, or not quite as loud. it's very in your face the way it stands right now.
The reason why it sounds unfinished to you is because you end the song effectively at 1:22. The whole piece just dies down, and never comes back up again. And yet it still staggers along for another minute almost.
That release is fine, good in fact, but you can't just drag that on forever! You need a climax that develops from it. When you bring the instruments back up, change keys, maybe add a new instrument, and then bring it back down to it's most basic elements (briefly), THEN the song will truely feel complete.
