Yeah, I second the notion that the piano needs to be a little bit less forward/bright in the mix. Throw some verb on that bitch!
Past that, this is really really good. I feel like you could do a little bit more with your drum fills/transitions to better match the level of energy of the rest of the track. For example, your snare is super-muffled which works sometimes, but for the more dramatic parts it just comes off as weak.
I'm really digging the vibe, this is one of your most epic, glorious arrangements to date, it did start to drag just a little bit toward the end when the overall song didn't increase in energy. As-is, this would probably still be a pass, but it could definitely stand to have a little bit more dynamics as far as the energy level goes. Make what you will of that, I still really enjoyed this! The Gerudo Valley sections particularly sounded great
