I don’t really care how pretty or ugly people make their characters, I don’t think one is better than the other or that an ugly design automatically makes an OC “better” than an OC with a more generally pleasing visual design. I care more about how much fun and enjoyment and investment the creator is having with their harmless fictional OCs. You can literally just make your own OCs if the OCs of others are not appealing to your particular interests or standards, not that any character exists to live up to these standards but your own OCs, so just make your own.
