Not bad
I didn't love the intro arp but at :22 I liked the synth you brought in and it sounded very good with the arp at that point, they mixed very well.
The high pad at the beginning wasn't too great, it added a bit to the song but the progression sounded a little off for the mood of this song. . .
Transition to 136 wasn't too bad, but the synth there didn't mix well into the arp from the beginning. The lower pad sounded good and the high pad again didn't seem to fit the mood the arp gave the song, it seemed like the arp was a lonely sound and the pad was a solo standing against a group, both sound lonely but one has a more heroic feel, which is cool they just don't mix well.
Interlude at 4 minutes-ish was great, not too much critique on that.
The ending sounded a little too much like the ending and got to feeling repetitive but I liked the Booooom outro sound, it goes with the feel of the song.
Don't get me wrong I liked the song, but these are all the things that you might could improve to make it awesome.
