it was really my pleasure! i'm not sure where you're writing your music, but something i've found helpful in terms of keeping good clarity in your mix:
1. you can try to use an eq to lower the volume of lower frequencies in certain instruments - i would recommend doing this for any instruments that don't have any important sonic information in that low register. for example, if your were using flutes, you could eliminate a lot of the low frequencies without changing the character of the instrument... this is especially helpful with any noisy samples of recordings!
2. you can also try to be really intentional about your composition! multiple lower register instruments playing different lines tend to clash a lot more than higher register instruments, so avoiding too many different melodic and/or harmonic ideas in the bass region can really be helpful! if you really want the character of multiple bass instruments at once, you can always try them in unison/octave apart!
i'm not sure if you genuinely were looking for a how to with this, but hopefully this helps you/anyone else who stumbles across this! again, i'm not an expert though, and the best thing you can do is just take a break from listening to your project, and come back later with fresh ears! :)
(but again, i have to reiterate: your project was so well done and fun to listen to!)
