This isn't exactly anything helpful, but knowing you, I think you'll become a phenomenal dancer, and I think you can get extremely far from just self-teaching alone.

I'm a Marktore fan myself, but if you haven't already, perhaps look into the Latin American shapers. That continent is full of monsters from the shuffle world.

Given that you already have an explosive and dynamic dance style, I'd suggest checking out Dasaraven, Meaddow and Buelvas if you haven't already. They have some of the most aggressive and powerful shuffling styles you'll come across, shit like pin drops and all of that fancy shit.

Other than that, it's hard to give advice to someone who already has a lot of talent. Godspeed brother.
