My biggest concern is the clashing of different keys

I was working on a song but it was turning out pretty shitty and I might just forget the whole thing, I have a private link that will take you to the unfinished song. Could you let me know if I should scrap the whole song and work on something else or keep working on it? https://youtu.be/58Xb7AQYLJo?si=VzQBUK-0NxoBuh73
