If you're having this problem with your DAW of quiet mix output, check your master channel and set it to zero. See what dB it's throwing out with all your FX and master comp on. If it's still low like this, but it sounds loud, check your audio driver and make sure it has no enhancements on My previous win 10 machine had realtek drivers which automatically and irreversibly compressed your audio for gaming reasons. I had to install a new audio driver, the HD Audio default sound driver for windows devs or whatever.
Alternatively, you can master your song in Audacity, which is free but kinda hard tbh.
I would honestly just move from bandlab to a more pro friendly program. Myself, I use Mixcraft.
But to an actual review, you already know the song is quiet, unmastered. I'll say I love your bass. Very tasty. The mix is fairly balanced, enough not to bother with going into too much.
Your breaks can get a little repetitive but they are chopped in an interesting way. The samples themselves suffer a bit with time distortion and are artefacting a bit from that plus pitching. That's ok. It's kinda the stereotypical sound of the genre. What I will say for them is that they could use transient shaping and potentially some crispy clipping.
Beyond that, nice little piece!
