Great end result! Although I'd find the raw sounds of the lathe and wood being slowly eaten away way more satisfying than listening to that music you put over video.
I'd suggest rather than taking the power sander to the charred wood, and sanding through all the charring, just use some steel wool or Scotchbrite. But the finished bowl looks really cool.
Nice piece of timber A few tips , take off the silicone bracelets and put them in your pocket , place some news paper on bed ways when using aerosol finishes , it saves scrubbing the bed with solvents and abrasives . the sound track is distracting . A voice over naration of what wood and tools you are using , what techniques , what products you are using Finished bowl is nice
