A subtlety that could perhaps be considered part of the aesthetic of a character is the way that they move. this is clearest in comics, but still comes through when writing their mannerisms at all, and I think it helps give a clear impression of the character almost as much, if not more, than what they actually look like.
For instance, Mrs. Moon has a habit of waving her hand when she talks that draws attention because her nails are always elegantly painted. Despite being very young and handsome (looking like a model honestly) Kattar struggles to walk, so when he does, he's bent over and his movements are described as being like those of an old man, providing a drastic contrast between his literal age and his physical health, maybe even the way that his injury has aged him emotionally.
“I don’t,” Mrs. Moon replies airily before I can even pass on the message, “Jun texted me and told me to pull up the news on my computer. You’re blowing up the internet right now, darling. All the art journals are tripping over themselves to be the first to say something about you. If we’re not careful you may take over the entire art scene, and your schedule will be too packed for me.”
I imagine I can see her waving one of her manicured hands like a pant-suited queen as her bright laughter sparkles through the cell like shards of diamond, but it feels a million miles away - her last words still churning and crashing through my psyche without registering.
Instead, I see Kattar, standing - and that’s enough to leave me flabbergasted - make me wonder if I’m not dreaming again - but then I see how hard he’s leaning on the dining room table, the walker knocked over on its side like it fainted-
And he’s crying…face flushed up to the roots his hair, now grown out, framing and clinging to his face like black damask as the choked breathless sobs wring themselves from his lungs - and thin rivers of glass, like hairline cracks, stream down his pointed nose and plummet onto the polished wood shining like a mirror - a mahogany ocean.
I don’t think I’ve ever seen him look so fragile and beautiful, and for one fraction of a second, that powerful urge to kiss him tears me in half - and my heart in two-
-I should go over to him - and give in. I should stay right here-
