EPIC
Great song!
The piano peaks, you should use a limiter (or a mastering) to avoid the noise.
Unless that detail, it's a really good song.
Efficient use of the timpani, you may try to use another pizzicato string to cut it.
Also, bring more cellos (or a layer of french horn) in the background would give it more depth.
At 1:25, it could suggest you to use a Choir
Keep up the good work :)
