The Power to Rise - Imaginary Game OST

Here's my first finished game OST for an imaginary game for a game jam. This is a final boss music showing off a kind person that had to do what must be done in order to make sure his people are safe, and that means he'll even turn evil. The OST would be a remix of the opening theme of the game which that opening would be called "The Power to Strive." Please let me know on what I could work on as this is my first published ost.
