I don’t really know why. It was never a problem until the reboot. Maybe they struggle reinterpreting her precisely because she’s so iconic. For Cosmos they seem to be having her the ‘serene’ and ‘droopy eye’ look that’s usually reserved for characters like Ami or Serenity. That being said they also gave her the Mars cat eye recently so who knows at this point. I’ve given up at any hope of consistency.
Same with Ami. You couldn’t think short hair would cause them much trouble but her hair differs -so- much. Even in the 90s anime.
IMO face was fine; its little off from character design sheet but its not error-wise bad its just little different; most if time i like face of that merch artist draws on Usa
(and again fixing professional's work when you worked with studio is so unethical of him; he shouldnt do it on his main account atleast)
