Drawn in ultra-realistic detail、An old philosopher with a profound expression

Drawn in ultra-realistic detail、An old philosopher with a profound expression。White hair and long beard、Wrinkled face。Wise eyes reflect a state of contemplation、Wearing old-fashioned glasses。His outfit is simple and classic, a shirt and vest.、In the background is a study with bookshelves lined up。High image quality and fine details、Images with clear contrast between light and shadow。
