Hi, Chay.
Denisse does a fine job with this.

I'm not sure what issue you've got, because it sounds good. As Bud mentioned, the
real work happens in the mix.
To quote Google's AI summary, mastering "polishes the final mix, making it sound its best across different playback devices and ensuring a consistent, cohesive sound."
Assuming the mix is good, there are quite a few tools that will get you that sparkle that's associated with mastering. Most of the mastering tools will focus on bringing your mix into a generally accepted EQ curve. You can also adjust the EQ of the stems to help them fit into the mix better, such as adding high pass filters to everything but the bass so there's not a lot of buildup of low-frequencies that can create muddy mixes. Figuring out where you want specific elements to sit in the mix, and then bandpassing them so they stay out of other tracks is another common action.
TrackSpacer is a neat tool for carving harmonic space out of other tracks so they don't mask important tracks. It's one of my favorite plugins.
I haven't tried Waves'
Curves AQ, but it's on my To-Do list. It automates the things I mentioned, and even seems to have functionality like TrackSpacer.
But really, the mix sounds good.
