This is not a genre I typically enjoy, however, I praise your tactful mixing and arrangement. The piano sounds lush and atmospheric. Only a bit more sonic blending and contrast between intro and mid sections, and this would shine gloriously.
2:40 strings show as hybrid cinematic it sounds like. I think the choir past that point sticks out a bit as synthy and laying over top the rest of the mix. Needs to be spread a bit more. The rest of your elements sound gorgeous. Only need a bit more balancing, less reverb, and more attention paid there. The final chord choice is a confusing one for me. Could be resolved to major 1 chord with heavy 3rd
