It might sound weird, but his inability to regularly score from free kicks is quite organic for him. Most of the great free-kick takers have that free-flowing improvisation in their style of playing, while Ronaldo is more about being a perfect machine, with a strict operating system, that lacks the necessary option to relax and improvise. Even when he scores from free kicks, his free kicks are usually quite direct and simple in terms of their geometry. Yes, they might be powerful and precise, but still, it's a different kind of goals compared to what, say, Dybala can deliver when he has a chance.
