I'm not sure if it's a western comic art thing, but there was for a long while many debates over skipping roughs, which would be the pass of making corrections and proportional adjustments across the board. A lot of artists skip the rough art phase because they stylistic approach characters proportions (or don't care), and the detail is going to get covered up by inker and colors, plus the style is extra minimalist. Not sure how much of a difference it makes having a separate penciler vs inker vs colorer, and how tight and Shift-left approach.
