To me, there is not a “right” or “wrong” way to present drawings. It is all about specifications & preferences: your customer’s specs, your company’s specs, and finally your own personal preference.
There are many ways which are good, and thus might well be called 'right' depending on the circumstances.
There are also plenty of ways which are unquestionably bad enough to be called 'wrong.' Drawn in sharpie on a set of napkins, for example.
