I really like the song
I think the song is really going somewhere.
In the way of criticism, I think the song actually has to go somewhere. At 1:39 is where I feel the most energy right now, and it feels as if that is the end of the intro, whether that is intended or not. I think the piano section after that (2:07) has an amazing ethereal quality to it, and I think it's a nice cool down after the building up of the intro; however, I don't think you should stick on it for too long, despite how beautiful it sounds. Really, at 3:00, you could hit the piano's last note fairly strong (sforzando), let the piano fade, and have the synths quickly get soft (subito piano), and gradually let them get louder (crescendo), leading into 3:04, where you could introduce a more relentless aspect of the song, especially since the suspended chord turns major (if my ears don't mistake me), making an excellent transition.
That's only what I feel, and I'm not such a great composer (if I could be considered one at all), so if you can come up with something more creative, or want to pursue a different direction for the song, do it, it's your song.
Personally, though, I have to admit that if the song remained so light all the way through, I'd appreciate the song, but would probably get bored of it fairly quickly.
Fortunately, it seems that so far, you have the capabilities to build energy and introduce variety, so I think the song will turn out well.
I hope you continue to pursue this song, because it has a lot of potential, and could end up being one of my favorite songs on this portal. The themes are great, and I think that you can take them far.
I can't wait to hear the entire song! Keep up the good work!
