Mm, it's difficult without familiarity with the music of the specific world.

[ he switches something from genshin. idk maybe yun jin's opera for dramatics sake. it sounds professional for something he's playing mostly by ear and maybe reading the sheet music a whole singular time ]

Liyue according to those familiar, has strong similarities to Cang Jing Peak. Thus it is not hard to imagine the music too would follow similar themes.

[ switching again to something modern again, it's clear there's less ease of playing cause he has to actually take extra time to figure out his notes as he plays. ]

Otherwise, even this one has trouble.
