I have decided to analyze these chibi pictures you have all offered me! I L

VE how this thread has turned into posting Chibi pictures instead of posting literary advice!!!

I mean this genuinely! GOING WITH THE FLOW AND ENJOYING ALL OF THIS WONDERFUL ART!!!
Eating chibi: a simple line with cheek curves, with bunny-like hands/mitts
Side note for Chibi: eyelids can disappear. Eyes are capable of turning into various shapes. Eyes tend to an oval shape for base eye structure.
Angry chibi: slanted eyes filled with white, along with popping-out emoticon.
Clothes tend to have an excessive (but enjoyable) amount of minor details, such as pins, chains, bows, jewelry, ribbons, etc.
Blocky shading techniques. No sharp edges and typically thick lining.
How does one describe that 'o' of a mouth?! It's not an circle, so an 'o' is SUPER INACCURATE!! What frickin' shape is that?! It's like an irregular bean!

Gloss on hair. Solid colors can stand in for detail.
Eyebrows are often really small and closer to the active muscles in the forehead. Oh! Oh! Edit: they are visible through hair, and are detachable with surprise, defying reality!
Often has a tangled mess of hair that is simplified to a point that makes it look interesting and aesthetically pleasing.
Base face: upside down 'v'
Maybe that 'o' of a mouth is an irregular 'v' connected by arcs? Possibly?!?!?!
As
@Stealthy_Enigma has just commented as of me typing this, crossing into realism makes it not chibi. Keep horns, scars, hairstyles, clothing styles, and other defining features.
Typically, if blush did not exist prior, blush is often added to the cheeks. The variation in blush is strange and cool at the same time.
Thick strokes paralleling the arc of the upper-right curves of the eyes add exhaustion.
Ombre effects seem to be common, lighter to darker and vice versa. Curious...?
Clothing styles, I'm certain of this, can be summer clothes, but tend to full-body, more wintry clothes. More canvas for defining characteristics as
@Stealthy_Enigma mentioned.
Fangs tend to become nubs that are the same color as skin, with varying levels of separation from face.
Eyelashes become solid, with triangles.
Model facial structure based off of bao/dumplings like
@tiaf mentioned.
VITAL CHARACTERISTICS AS EVERYONE HAS MENTIONED: stubby legs, child-fied, round and tiny, cute, big eyes, big head, simplified, slight chubbiness
