Janne, well, THAT's a sad story, isn't it? Lovely melody and backing track! The vocal arrangement is quite nice, too. My only suggestion is to perhaps improve the vocaloid performances. They hit all the right notes but sound a little too perfect and unnatural. I don't know anything about vocaloid programming so ignore me if this is off base. Really enjoyed your sad-but-beautiful song!
Thanks DC for your positive comment

Well, I wouldn't call it a sad story when it ends with a smile

You are right about vocal being little too perfect, in this case I think the midi melody was already quite quantized when I imported it from Vocaloid to Synth V and the tempo is quite slow so the unnatural feeling is more clearly present. I usually don't quantize that much if I have played the melody directly via keyboard.
