I'm not sure what we're being asked if we can tell or not. Cant we tell that Johan O is far too good?
Actually I'd say this video is a pretty clear reassuring of that fact. Johan always kills it, not only with some amazing hammers but such a nice flowy style to top it all off. It's great to see videos where desk footage gets turned into soo much more simply by the way it's put together too.
Go check Johan's channel here :)
