Ha! I knew I heard Rachmaninoff influence. I thought some of it also sounded kind of Gershwin-esque as well, which would also fit. Since Genshin Impact was an influence, you could have this "Gershwin Impact."
Overall I thought it was very good and shows a lot of ability to use dissonance in a complex way.
One thing I might add as a constructive feedback is that there's kind of a vertical similarity throughout the piece, in that it feels kind of busy throughout the whole thing, without being punctuated by variations in overall amount of sounds happening at once.
Overall, very good work!
