Some great edits here. It's kind of interesting to see when people draw faces, because they'll often mess up proportions based on how much attention certain features (e.g. eyes, nose and mouth) takes up in their mind. They'll shorten everything above the eyebrows, for example, because they're not hardwired to pay much attention to that part of the head. But people are hardwired to pay attention to people's eyes, so they draw them bigger.
My two cents on this topic:
"Right" might apply to idealized photorealism and how everything is drawn "idealistically right". However in reality there are lots of tiny and not so tiny differences in faces which just give the person a certain look and that's usually quite far apart from what the classical idealized notes on anatomy tell us.
Let's say Loomis' Figure - compared to a "real" skeleton/human it's strongly idealized in some aspects.
While unintentionally shortening everything above the eyebrows might make a Loomis figure odd, it could be fitting for a caveman-character and clearly underlines that he won't have a lot of intelligence (just sayin)
Same goes for the eyes - drawing bigger eyes can lead to another impression of a character than having small eyes - just considering why most anime styles tend to have huge eyes and no noses.
It's something I struggled a lot with, but limiting yourself on the "right" proportions which are "idealized" can definitely lead to very boring and exchangable cast of characters with very less overall diversity - it just makes one archetype so to say, while for character design diversity is key.
It's a mighty tool to know a lot of the proportions to each other and be able to cross-check them, that one exactly knows where he/she is exaggerating and where not.
However correct proportions and photorealism can get an end in itself if it comes down that the goal is to add a lot of character to a human figure rather than a realistic depiction of a subject.
Getting the meaning across can be handled much more effective with a less realistic style, which just emphasizes on the details one needs to communicate and exaggerate those to make it even clearer.
Because the more realistic all gets the more it will be received as realistic and the less realistic it is the more can get broken regarding to proportions and flow of the pose - then it's just a matter of the right balance of the level of stylization the style one goes for has.
A lot of cramped in detail also can turn out ugly if it's something a particular person don't likes.
Let's just say I dislike skinny women (which is of course a highly personal opinion) and then I look at nights edit where the ribs are drawn in. The ribs are actually there in reality but only if the overall body fat is really low - so I will dislike it because I dislike that type of realistic figure. If the ribs weren't in a t all that question might never come up.
The more important question the artist should ask is what does he gain from drawing them in if the goal is not just illustrate the detail for the sake of detail, but in order to communicate a well-thought-out character.
To pull off those considerations of stylization really effectively one needs to have a strong understanding of realism, while it might never be as explicitely shown in the final stylized illustration.
The goal here clearly wasn't realism at all. But Satsume, you might really benefit from doing some realistic studies and applying some of the observations you make there to your stylized work.
