Best way imo is to just be yourself! Especially if these guys are already supporting your shit then a simple DM and being chill about smth can really do a lot. If your dm doesn't get seen then you can always send an email to mgmt or the artist. Always gotta remember these big artists are normal human beings just like you, so no need to be nervous talking to them or overthink about what to say. Just vibe and do your thing :)

Proud of you brother 🤝

This is so good bro I love this Maybe try messing w the drops and going for a more "airy" saw sound. Giving it a more lighter and fluffy feel on top w the slight grit from the bass could be a cool sound Def try some vox chops, arps, plucks, etc. that come in for only like 2-4 beats in the drop! Can add a lot of expression and bring some new feels in. I think maybe a different kick could also be nice for the drop. Something a little more "stomp-y" feeling if that makes sense. In my mind i'm just thinking about the old illenium kicks pretty much Keep it up brotha 🤝
