My track would probably be rejected...

Hi, I’ve been comparing my track:

Cumulus Music · Summer Jazz 2025 22 Jul

with an existing AJ track, which has a similar vibe/audience:

and I can totally see why this one is better on so many levels. It sounds clean, spacious, where mine is boxy, cluttered. In my studio mine sounds OK, in fact I like it a lot, but when I compare them on laptop speakers I can hear a huge difference.
Can anybody hear specific improvements I could make?
Thanks in advance.
