I think this is the most faithful entry I've come across; the choice of instrumentation and arrangement is so wonderfully and thoughtfully put together. Emotionally it kind of keeps me on my toes - I'm not quite sure what feeling to lock into, but that kind of ambiguousness can be a boon when done correctly. Easy to forcibly instil happiness and sadness, but striking the balance between can be difficult to do well.
The ending sequence is a neat little touch and, in all honesty, I would've liked to hear it expanded upon a little bit. Could even work as a separate entry altogether, but I digress. Very well done - this is nothing short of exquisite. Thematically on point and arranged to perfection. As Starsickle said - I would've loved to hear more! Best of luck in the competition. :)
