This is a nice cinematic depiction of the scene! I feel the motif and general vibe captures the feeling of hope well. The setting of the story is mostly gloomy, but the scene where Corvin is empowered by the spirits gives hope to the oppressed, and it's great how you focused on that feeling.
I like how clean the mix is, and the brightness of the drums and strings. You did a good job with the sound design and atmosphere too!
At 2:42, it sounds like there's supposed to be a huge climax, but the momentum suddenly stops because the arrangement lacks bass, the dynamics are flat, and the drum rhythm is relaxed and doing its own thing. It feels like an interlude in the battle section, but the execution of it doesn't really work for me. In this kind of situation, the orchestra could benefit from dynamic swells, going from soft to loud, some movement in the texture, like woodwind or harp runs, and percussion that accents the swells.
I like the outro. It reinforced that hopeful vibe and has a satisfying ending :)
Overall, I think you did a good job conceptualizing the track and there's a lot to like with the atmosphere and sound design. The orchestration can be improved, but this is a good start considering it's new to you. Keep it up!
