How To Make Bass Tremolos Pop (Without Sounding Dry)?

So I'm working on a section of my song wherein both the cellos & the double basses are performing a rhythm of tremolos while the other instruments play the melody.

This is what I envision the sound to be like (from Kung Fu Panda 2's "Po Finds the Truth")

However, my work sounds dry. Although the section I'm working on does the tremolos, it just severely lacks and further reverb/bass , and I don't know any techniques I can employ (either on the sheet music or the Mixer).

I've attached my work below so you may look into it and provide feedback.

More info about the MSCZ file (to retain its structure on your computer):
- Last Updated on MuseScore v4.4.4
- MuseSounds is the only sound font used here (only that)
- Mixer uses "ShapeIt" plugin by Soundly from Muse Hub (I've attached the XML preset below for you to drop on "\Documents\Soundly\Shape it\User Presets\")

Thanks for your feedback in advance!
