Can anyone tell why my mix sound that waaaay different from the refference?

Well, here's the thing: Despite some aesthetic differences I think the structures of both songs are quite similar but at the same they sound totally different, like, the refference one sounds tremendously clear while mine it's having a really hard time finding every instrument it space, I think I'm doing things right but clearly there's something waaaay wrong.

Here's the refference track: KAMADA - ANEXOS DEL OTRO - YouTube
