In the first picture Zagreus is shorter than Persephone because he is standing one step below, he is still the youngest member of the family and barely stepping into his role on the house as Prince. He is supperposed with the image of his parents gazing lovingly into each other, he is integrated with his figures but still feels like slightly distanced from them, like a teenager trying to find the way they present themselves. After seeing him the whole game with other clothes it feels weird to see him wearing that tunic and his lance is comically big.
In the second picture he is taller than his mom and almost at the same level as his father, he is being embraced by him but his head points out from Hades's shoulder, he is fully integrated into the family but is also respected and acknowledged by all the gods as the one who reunited them. He mimics the posture of both his mother and father, leaning over Melinoë (bathing in her light) and embracing her with his hand (ready to protect her). His elegant clothes fit him and resemble the style of the Palace, even without his crown you recognise him as a Prince of Hades.
He grew up so much between this games. Probably embraced his role as a protector of the underworld population. Seems comfortable wearing his father clothes, he holds himself with authority, he earned respect in his realm. He became an adult. He loved his little sister, look at how his gazed is fixed on her, his smile might be even bigger than the one on his mother.
Hades looks peaceful and calm, he is probably smiling too. Persephone is wearing a light dress, similar to the ones she wore on the surface, without obligations. She wrapped her daughter with a shawl like the ones she used to wear. They are all dressed without their "royal" outfits. Before being the underworld rulers, they are a family welcoming a baby. They loved Melinoë so much. They would have devoted their lives to her until she was old enough to stand on her own. They would have given her all of the time of the day. They were ready to do things right this time.
But our Airplane who is just some fucking guy and is constantly compared to a hamster
In canon he is described by Cucumber as good looking if kinda sleazy
He would look like one of those sexy characters who you know would sell you out for a corn chip but somehow repeatedly talks his way into your bed and into mooching off you
He does work it's incredibly shady but he can also charm his way out of situations and manipulate his way out of ones where charm fails
You get the feeling he's always at least a little amused at you
You can't catch him at anything but you find yourself slightly paranoid in his presence. At first concerned for your wallet and later concern of what he knows
I'm just saying that he has a following on An Ding, every merchant he has ever talked to wants to ruin their life by fucking him, and it's not a wonder that Mobei Jun wants to be taken roughly by him to the point its getting sad
And I 100% think Shang Qinghua doesn't realise he has these vibes
It also doesn't work on the other peak lords because they have seen him in a fight and also on the day the expense report is due
They know him at both his most embarrassing and his most terrifying
