Absolutely! Finding the fine line of creating a strong instrumental blend but also having each instrument stand out can be a bit difficult, one way you can help create that heavy effect can be experimenting with having those instruments all play elements of the same chord but in different registers (think of how in a large strings section the violins still can play notes in the same chord as the cellos but they wont be the same pitch) to help broaden that sound, because what i mean my mashed together is that since so many different instruments are playing the same notes in the same frequencies it can make it a bit muddied to the listener, take for example how the opening shots in Decisive Battle II from Octopath traveler sound super heavy, with a lot of that being the size of the chord and how much each instrument stands out creating a richer more dynamic texture. Hope this makes sense, still good work i just wanted to clarify what i was saying more :)
