Left: Jung Yonghwa ('s beatboxing) to me, is like a diamond in the rough.

He's got the basic sounds and a range of techniques.

(it would be nice) if he makes it longer and creates a set of composition.

I would say his sounds, the basic skills by itself, are top-class. 

What do you think?

 

Right: He has great basic skills. 

What impressed me was that he has a very wide range of expressions.

He used click-clop and click-roll, from the video you saw. 

And things like the breathing technique. 

From these sessions, it looks like he's been into beatboxing for a while.

I'd say he has practiced a lot. 

 

Left: With this, we pick Jung Yonghwa as Top 4.
