Arafed man with a beard and glasses making a funny face

"Create a detailed avatar of a geeky man with long, messy blonde hair and an unkempt, scruffy beard. His nickname is 'El Barbas.' His face shows yellowed, crooked teeth with noticeable gaps, emphasizing his poor dental hygiene. His appearance is very dirty and disheveled, giving off a strong sense of being unhygienic and possibly malodorous. He has a wide, almost chaotic grin, sometimes referred to as a 'trayao' smile. His blue eyes have a vacant, slightly unfocused gaze, adding an autistic spectrum vibe to his expression. He wears round, somewhat crooked glasses that sit unevenly on his nose. His clothing is wrinkled, stained, and generally unkempt, reinforcing his overall lack of cleanliness. The background should be simple and neutral to emphasize the character's features and quirky personality."
