This question involves aesthetics and personal preference, so there is no absolute answer. People with a beeping mouth and people without a beeping mouth can be beautiful, mainly depending on personal understanding and preferences of beauty. People with a beeping mouth may give people a lovely and lively feeling, while people without a beeping mouth may be more mature. Beauty is a subjective feeling, and everyone has different definitions and preferences for beauty. Therefore, it is impossible to evaluate a person's beauty and ugliness, whether there is a doodle or not.
