I like this approach better from a design point, being a character artist. I think it's a good point you make, everything it's place. I've learned a lot of different methods for drawing, construction methods, visual measuring, building from the outside in etc...I have been trying to think of a way to merge them, to come up with my "go to" approach. Maybe that's a mistake though, maybe what I should think instead is with that understanding, I can chose the approach based on what the drawing problem I need to solve is.
