Beautiful soundtrack overall. Love the depth on the various string articulations, from the pizzicato in "Sujin" to the big staccato notes in "Faith," the strings do a great job of filling in the space in your mix. in a fulfilling way. Your snare might be just a bit too present and powerful towards the beginning of Prove Yourself, but it feels a bit more balanced out with the rest of the mix towards the latter half. Would have liked to see some more variation in this track overall, it's great up to around 0:46, but the energy dies down a little TOO much to keep the battle energy going. A little more emphasis on the drums here, maybe a fast, low snare roll, could help to keep things moving.
Overall, great soundtrack with beautiful orchestration. Excellent work!
