The large "must make boss battle theme" mindset in my brain took over when I was working on it. It started off pretty okay, with the main battle theme, then leading to Imtalia and Sheriff Fella's themes. Although, once it got to Imtalia's, I kinda made the rest of it be in a minor key. Leads to King J's theme, which I do think fits because he plays piano a lot. The rest of it however, kinda goes into a more "rock-like" vibe, in more emotional bits for... some reason. I dunno why.
