Earlier quoted context omitted.
I’m sorry but as a pilot who routinely uses airport diagrams what specific weakness are you seeing? As you are probably aware, not all maps are intended to have some beautiful aesthetic. This map is quite akin in style to the layout of airport maps (diagrams) published for actual pilot use.
I'm confused why it shows detail like holding position markings, but not taxiways or hot spots. And it conflates locations using different hold short markings (ILS and runway).
Edit: it does appear that hold lines are mis-tagged in some spots, e.g. north of arrival end 25C.
