/ic/ - Artwork/Critique

One thing that always confuses about manga artists is when they draw 6 fingers, an extra hand or the thumb on the wrong side. This error is just too pervasive, much more than in western artists.

Why does this happens?

After watching A LOT of japanese live streams I've noticed that most artists don't do construction sketches or use perspective lines.

In fact, the majority jump to the "polished" lineart from scratch. Which leads me to think that the "mindset" among them is mostly raw memorization of symbols.

That is indeed a very japanese mindset, as opposed to the west in which constructivism and Bloom's taxonomy are the norm and pure rote memorization is considered "crippling" in terms of understanding how things works.

And I agree with that on math and programming. A mathematician NEEDS to understand how does the formulas work instead of just merely applying them.

But in the ARTS a huge chunk of information is memorization of facts and rules, whether it is in music or painting.
An artist must take a shitload of decisions, and during execution you cannot construct and consciously elaborate on every single detail. You have to let pure memorization take control in many aspects or you'll will never get anything done.

I think I'm going on a tangent, but my question is. How do you improve the system of visual memory and how do you prevent it from stiffing spontaneity?
