You know, I think I'd enjoy such a movie.

you know....... i'd like to see an artist actually do a study where they legit draw AI style art
like they draw what looks at first glance like a perfectly nromal piece of art, but then you look closer and it's got all this wrongness about it.... and it's the exact sort of wrongness AI art has, but you can see the brush strokes the shading the infill, and it's clear that it's not an AI that's generated this..... someone actually made this art look like that on purpose.

@HardwareGeek Just noticed - she's pulling back on the arrow, not the bow string - them's some strong fingers!

She only has one finger on the arrow, sort of, and it's going through the arrow. And don't you normally generate most of the force by pushing out on the stave, not pulling back?

I mean, there's lots of "wrong" things in there, I just noticed she wasn't pulling back on the string.

When I learned archery about 45 years ago, I was taught to hold the bow loosely at arm's length, with the elbow rotated out, not down (with all that is hideously wrong in that picture, the AI somehow managed to get that right), and pull the string to my face. (There's a reason why the action is called drawing the bow, not pushing it.) I learned to anchor with my forefinger along my jawline, my thumb tucked underneath, and the bowstring touching the center of my lips, but lots of people use their cheekbone as their anchor point; it doesn't matter, as long as you're very consistent.
Incidentally, she's holding the bow in her right hand, which would indicate she's left-handed, and drawing the bowstring with what should be her left hand, if the AI had the slightest understanding of anatomy. Of course, drawing it with her left hand, she should be drawing it to her left cheek, but that's far from the worst error the AI made.

@topspin Pfft. She's not pulling the bowstring to her cheek or lips.

The forces are the same (magnitude, opposite direction), because they ultimately need to cancel each other out. But the hand holding the stave is outstretched with joints locked, so the bones hold the force without much contribution from the muscles. The muscles that do most of the work are the back ones as the arches spreads out their arms.

What a fierce warrior woman who can manage her bow in any position, and did not have to cut away one of her its (original meaning of
amazon). Wow!

Sir Isaac says yes.
But the hand holding the stave is outstretched with joints locked, so the bones hold the force without much contribution from the muscles.
If I remember my technique from decades ago, the elbow should be straight but not locked. The point, however, is that arm is always fully extended; the elbow is never bent. Drawing the bow begins with the arm straight, and all the pulling is done with the other arm.
The muscles that do most of the work are the back ones as the arches spreads out their arms.
The arm holding the bow is supported mostly by the trapezius, and I suppose by whatever the corresponding chest muscle is, lifting the weight in hand of the bow and arm against gravity. The force to draw the bow comes from the deltoid, teres, and maybe some from the latissimus and trapezius of the other shoulder pulling the upper arm backward.
The technique I learned for drawing and shooting a bow is as follows: Start by standing perpendicular to the target, with the shoulder of your non-dominant hand toward the target. Hold the bow at your side in your non-dominant hand. Nock the arrow, and hold the bowstring with the first 3 fingers of your dominant hand, index finger above the arrow, and the other 2 below it, and with the string in the groove of the first joint of your fingers. Don't pinch the arrow between them. Keeping your elbow straight, raise your non-dominant hand shoulder-high. Simultaneously pull your dominant hand to your face (cheek or chin, whatever your preferred anchor point is). Aim. Breathe out halfway. Relax your dominant hand, letting the string slip gently from your fingers.

That's certainly how Japanese archery (Kyūdō) does it. Most western archers don't use their backs so much (though they probably should be).
