Just downloaded it – I can hear what you mean and I know the sort of bass you want but I think that it may be difficult to get this without either loudspeakers or cans which can provide the bass response you want. Maybe if you put a small amount of reverb/delay on it (not too much) that will fatten up the sound.

BTW for more bass on monitor speakers I use two of them cheap “PA” cabs sold at CP set up in “Norfolk kiddie rig” style, they do the job…

Not sure where the compressor is or on what instruments but it does seem to have taken a big bite out of the dynamic range of the whole track…

Also is there any way you can set your DAW to 48 KHz sample rate and 24 bits (or more) per channel? Although 44k/16 bits is most common for distribution and broadcast if you can get more in production its worth doing. Even my mixes are recorded in analogue at 48 KHz 24 bit (though the source material is usually 16 bit) as the storage space isn’t loads more and it seems to sound just slightly better.

more about sample rates here…
