What is Luka's next point of progress? Luka has been progressing at a ridiculous rate year by year. In year 2 he became much better at finishing around the rim. Year 3 he developped much better shot and midrange. He also gradually became better defender. 

What is the next point of his progression?

In my opinion it is tightening his handle (though it is already really good) and cutting down on turnovers. I feel that he can still become better in that depart. Also, he can still become faster after losing some weight and still become a better defender, especially off ball.
