Create an illustration of a man with his hand on his chin, showing expression of concern. The man will be portrayed in a peaceful environment, como em uma sala ou ao ar livre. He will be wearing casual clothes, like a shirt and jeans. His hand will be resting on his chin, with fingers slightly curved and facial expression denoting concern and deep thought. Pay attention to the details of your facial features, como sobrancelhas franzidas, olhos ligeiramente fechados ou enrugamento na testa, to represent the concern convincingly. Use soft, delicate strokes to create subtle shadows on relevant areas of the face, giving greater depth and realism to the expression. The background will be simple, with neutral colors or subtle elements that do not distract the man's attention and his worried expression. The goal is to portray concern as a genuine feeling and convey the emotional intensity of that facial expression..
