This is quite happy, although I know where you're getting at with it :P Even though still I'm not totally sure whether I'd get "Sorrowed Tears" out of it. But now, let's focus on the song itself.
Very nice work! The atmosphere is nice, and you create it smoothly with the beginning there. I think the cello beginning somewhere around 00:30 is just about the volume where I would keep it. With a volume like that it creates a soft feeling to it. In the climax there should have been a string quartet, however. Would have emphasized the feeling even more.
All in all, a solid tune. 9/10 and a five ( 3.76 / 5.00 (+ 0.098) ).
