>But then I thought to myself, what kind of drawing does it take to see if someone is skilled or not?Depends on what you want to evaluate them: art is a complex skill. Ultimately, ask someone to draw a portrait in color with traditional material, purely from imagination, and to design the portrait in an appealing/original way (it's quite hard to do something really non-boring with a a portrait). Composition aside, it should be as good as if it has been made from life.
This would mean that the artist is able to invent a subject, lightning, have in his mind the anatomy of the face (skull, fat, muscles), has great composition skills, has great rendering skills (likely, developed by copying/drawing from life), and can handle color, and all the inherent difficulty of working with traditional mediums.
