As far as the song itself goes, I like everything except your choice of instruments! I feel like if you swapped out those thin-sounding synths for something a little sawwy/buzzy or a deep piano it would suit it a little better, although maybe that would give it a heavier sound then what you're going for.
Actually I think it's the flute that's throwing me off. Maybe consider swapping it for an ambient pad? It sounds a little out of place.
Also the crescendos spike a little bit!
Beyond that the melody and mix of elements is really neat! Good job with this. It's short and sweet.
