Wonderful track.
I like the slow progression on this track, but I encountered the first bump at 1:07. It's great until there, but there's something you can do to make the full drums introduction a lot better. The transition at 1:07 is lacking IMO.
You could try doing a very quick and sharp crescendo with a single synth and without drums seconds before you add the drums and you can also add a crash at 1:07, unless you don't want an explosive intro of drums.
You did something similar to the above at 2:48, which is nice. I like the choir that you began using in between those two points.
Overall, it's a very good, subtle track. Love the piano and the pads. Excellent automation job too.
Keep it up.
