The sprite drawing is coming through, soon enough to bring out the next track. This one draws even more inspiration from Octopath, not just the sprite style, but also the theming which is reminding of the "Determination" track most notable during Primrose´s final boss fight. That particular mood captured me and it was so motivating that I was just aiming to replicate that vibe. I guess it is accomplished even though differing due to the use of an electric guitar.
The sprite in this screen is Shara, a heroine of a mountain community. Most remarkable her adamant spear that she carries on her back and the red ruby embedded on her chest armor. What role might she play and why is she featured with this piece of music?
