Nifty...
I really like the strings in the intro. Cool sound there man. You really nailed the intro well.
Like the buildup to the near 0:50 mark, then it dies down a bit. Cool way to work that little transition. I like the section starting around the 1:10 mark, but I think you need to add something there to give it some flavor.
Yet again, a nice buildup to the 1:30-ish mark. And I like that section as it is perfectly. And the transition out of it was clean and smooth. And they a buildup to a grander string sound after all that, which is very pleasing to the ears.
Something to think about would be to add a few more sounds throughout the song. Nothing to extreme, but something to give it a little color. Because it has great horizontal depth. But is lacking a bit in vertical depth. A few more instruments throughout the song would do wonders for that.
I'm not crazy about how it loops. If it is a loop then fine, but songs really should have endings. And this is pretty long for a typical loop. And submitted it as a song, not a loop. So you should come up with a proper ending for the piece. All said though, this is a nicely constructed piece. 4/5 and 8/10 overall, because it is good. But not great yet. I think it has a little work still to be done.
Great job!

P.S. - If you change this later and resubmit it, let me know. I wanna hear what you changed in it. :-)
