text: I love this picture overall, but the audio cassette is too smooth to be believable. Look here: https://www.alamy.com/stock-photo/cassette-tape.html?sortBy=relevant
  Also, everything in the scene needs denser geometry. The scene is full of contours that should be smooth curves but actually appear segmented.
  Thank you for your very accurate observations. Actually, I decided many details later and wanted to finish it the same night. But maybe I will pay attention to what you said while preparing "Vol.2". Thanks again for sharing important notes for a new Blender user like me :)
  The 80's... Awesome times, and what awesome work. 👍
  Awesome. I guess the only thing is you can see the low resolution of the scratches in the close up shots. But it's only a minor nitpick, it looks great 🤘
  You are right, I actually tried a bit to solve the problem, but I guess I'm a bit of a "timeline diamond" guy :)))) The topic of Node and the "normal" of features still sounds complicated.
