New Modder - CC can't be seen on top of other objects

Hi guys! Apologies if this has been asked a few times. I'm a new modder.

(In-game screenshot) My confetti is going through all the objects. It's in front in the game but whenever there's an object, even at the back like those frames, it still appears in front.

PS. I might not have the best practices but here's the package file.

I'm also open to suggestions on how to make my modding better. Thanks a bunch! More power all~

EDIT: my base item is a rug if that helps
