Very nice documentary! It was a nice insight on Harry's works and his mindset behind them.
The only nitpicks i have with it is that I thought the audio balancing between Harry talking and the shorts shown could be a bit better, I felt like Harry and Joyce sounded a slightly lower than the other stuff shown. Also, I thought the last segment where he talks about the tools he used could have been better placed, I thought that the documentary had ended after the talk with Harry and Joyce and the HH logo showing up haha.
Aside from those observations, great work! Enjoyed it very much, keep it up!
