My Musical Arrangement

Currently, I'm listening to a lot of Conan Grey, Taylor Swift, Olivia Rodrigo, Tate McRae, and a lot of original music from TikTok creators. I decided to take some inspiration from these artists to start a musical arrangement. Basically, I just have the beginning of something done, so I'm far from finished. But this is what I have so far. I used MuseScore, and since I don't have the set up to record me actually playing, I used its preview function for you to get an idea of what it would sound like.
Though I am struggling with the last bit, I'm enjoying the process.
