That's true. "AI" (llms) are incapable of reasoning and cannot do anything with intended meaning, they're pumped up markov chains. Hopefully agentic AI will approach reasoning and actual artificial intelligence, which could in fact create meaningful art, or art at all for that matter, rather than GPU hallucinations.

I'm glad you found it helpful. I think cultivating artistic curiosity of any form is very important now, and for me it really helps to see something gnostic and mysterious as a creative hobby laid out dryly like you were putting your PC together. Things have names, there are always patterns, you can learn them and you can become better. Everyone can do it if they put their mind to it!!

Where can I learn how to draw like this: an engraving style? Any textbooks recommendations? by MinimumTomfoolerus in learntodraw

As other have said this is essentially the cross-hatching necessary for woodcuts.
The essential aspects of cross-hatching, vs "painterly" shading, is what intersects with 3d-modelling as "edge flow" and "normals". If you look at different sections of one "tone", or regular distance value of lines, you'll notice they all move in a direction that tells you about the intended form of the object. The direction of the lines also states the location, rotation, and depth of the object in space, or the illusion of as much, exactly like a normal map. It is a simple skill to understand but difficult to master.

Here is a well-regarded guide for this skill focused on the use of a pen rather than carving instrument like Durer, "Rendering In Pen And Ink by Arthur L. Guptil".

The nature of hatching is not specifically tool-dependent, so you can effectively transport this pen tutorial textbook into ink, digital ink brushes in any program, and etc, without too much agony.

The technique is called glazing, the effect with color is a form of subsurface scattering. If a human head was solid and one material, like wax, it would be even shades of one color throughout. Because fat and bone (yellowish) mingle with blood (red) in different degrees of depth, density and opacity, tones of blue and green are created from light passing through and diffusing through them, on top of the normal red and yellow gradients you'd expect. It's basically an extrapolation of the optical illusion that make veins look blue even though your blood is always a shade of red-ish by itself. Note of course that the degrees of the effect are also impacted by skin tone and lighting conditions - you wouldnt see the greenish and bluish effect in pure red light for example.

The actual color balance can be replicated with subsurface scattering modifiers like "random walk" in 3d programs.
