For a rhythm game, you shouldn't put the "great/miss" rating in the middle of the screen with such an impactful effect (it popped up to the screen). It also took up too much space. Combining the two together, it was a bit difficult for me to actually react to the notes falling down, since they speed up over time. The notes were not manually placed I think (correct me if I'm wrong) therefore it was understandable that they did not follow the beat/vocal/rhythm too well. Other than that, the background is nice, the music choice is very good! Would have loved another skin for the notes though. You can check out Osu! Mania (it's a game) for different note designs if you would like!
