Yeah, some critics about this feeling improvised, but guess what? it IS improvisation. Remember what hickey says about improvising? (https://www.infoq.com/presentations/Design-Composition-Performance/ https://www.infoq.com/presentations/Design-Composition-Perfo...) It is art and years of preparation right there performing real-time. So that guy criticizing is only auto declaring he is incapable of improvising on this matter.. and it's ok it's only for the best ones after all. It is called a challenge for a reason.
