I like how soft the marimba(?) sounds. The chord sequence is nice enough if a little cliched. But the song doesn't progress! We have the instrumentation build a little bit, the piano tinkles away and we get some sort of timpani/percussion. But melodically the song goes nowhere. Even if you didn't want to change the chord pattern you could at least have introduced some countermelodies or overlapping melodies that looped over a longer period than 4 bars. The note at 1:04 seems an unnecessary jump in pitch that doesn't flow from the single note repetition prelude it was given.
That said I like how all the instruments sound and the mixing seems good to me. As background music in a short film i'm sure it would do nicely. Certainly has a feel of rising and inspiring.
