Am I seeing some subtle Madness and Clockday references in the studio background there! :D
Pretty creative twist with the sketchbook thing here, and surprisingly well cut together too... at first. When you start seeing the hand flipping the pages the illusion kinda cuts away, though. I'm still entertained, but not sure that fourth wall bit was done the best way possible. If there be hands, at least he should've noticed those hands; interfaced in some way, IMO.
Otherwise good stuff. Sergio Show still going strong.
