Hello Giuseppe, I think you can try doing a little guitar asmr video lmao. As a master of palm-muted hybrid picking, I don't think anyone is better than you at this job. Those fast clean muted sounds are so soothing to listen to, just like the triggers in asmr videos. Make it stereo, add a little ambience, it would be easy and maybe youtube algorithms would dig it.
Love the camera angles and clarity of you videos. I wish I was tech savvy for that but I’m the play and go kinda guy. How many cameras are you using? And is it a Sony camera?
