Hey Chloie,
Fantastic work! I really enjoy the happy-fun-party vibe I am getting from your overall site. As Percy mentioned, it really does reminds me of something that I have seen/interacted with before when I was little kid growing up in the 2000s as well; so I really love how you captured that same feeling within your design. I find the little visual aid on the bottom of the shop page about the differences between the "Rising Star" and "Mega Star" packages to be very interesting and insightful, and adds a greater level of immersion to your fictional company.
Another detail that I liked was how the mal-e checkout page was customized, it fits in real nicely with the rest of your website's theme, and again, adds more to that level of immersion that this could actually serve as real retail site by having a text box where customers can personalize their orders. And judging from that, I can tell that a lot of dedication was put into building this website!
The only small concern that I do have is that I think you might be missing a contact page, since I cannot find one in your navigation bar. But looking past that, this was a very amazing and creative website to spend time exploring through
