Proko and Vilppu arent a replcament for that and vice versa. Being an artist is 15% theory, 70% observation, and 15% actual drawing. If you cant observe, you cant draw. Simple as that. Its not a new method, its literally how its done, Proko and Vilppu both recommend life drawings.
Thoery is there to help you understand what it IS you are drawing and how to manipulate it. It is part of the curriculum that helps creative drawing A.K.A drawing from imagination. Techniques and such. You dont HAVE to use those though, because observation will teach you much of this already. These lessons they teach are a result of observation.
For example, they OBSERVED how when a person turns his torso, his entire upper body moves in sync and back muscles stretch, and the pelvus gains an angle. They then simplify it down to shapes to better illustrate this point.
This is something learned in OBSERVATION. Theory is the result of lessons learned from Observation.
Kim Jung Gi also teaches Thoery by Observation. Look up his classes. You know what he draws to students? Boxes. Because he uses simple shapes to get across a point he learned from Observing.
Theory is literally someone else's "Aha, so that's how it works!" He learned by observing.
