Linux - have you had lessons / coaching from someone who s qualified? And I don't mean a friend who everyone thinks rips - but an IT, ITE, national team coach, senior national team member, etc.
I find that those who have difficulty transitioning to more advanced moves have not mastered the basics. In the two sports that I teach (paddling and alpine skiing) it all boils down to executing a very few basic things properly, to the point of obsessiveness. Those who appear to move effortlessly like silk in the wind have just really, really dialed the basics so that doing essential drills are like breathing in their sleep.
Enjoy the journey.
