Overall, I like the song. It rises and falls, taking your mood and heart rate with it in the process (metaphorically of course). It's mellow, not very climactic, but still manages to I guess "pulse" you with minimal melodies and instruments.
But I have a challenge for you, if you want a challenge...
I've been trying to find/create/discover a music of the future. Obviously, this is open to a lot of interpretation (considering any time period has a number of genres), but I have heard some songs that could fit into this category, songs that push beyond the boundaries of specific genres. So, if you want to have a go at it, I'd like to see what you'd make of it (of course, if you want to or are feeling it). I think you could make some interesting stuff with this concept in mind.
