I love watching these, and this is the latest and most dramatic.  I don’t have the chemistry background to be a full on restorer, but it would be rad as fuck to be a retoucher.  This is the only one I’ve seen use this sketch technique, and he did another one in which the eye was not working At The Fuck All, but I find these both soothing and kind of inspiring, like damn, yeah, that would be a great job.
