Create a detailed portrait of an older man with a long, flowing white beard wearing a vibrant red floral-patterned jacket, a gold medallion necklace, and a yellow wide-brimmed hat. The man sits in a relaxed yet commanding pose, with one hand raised. He wears reflective sunglasses, adding a modern twist to his antique, regal look. The background features impressionistic, colorful brushstrokes, adding artistic depth. Use soft, even lighting to highlight the subject's features and rich textures in his clothing. Medium: digital painting with oil painting textures. Incorporate subtle Photoshop effects such as HDR and color grading to enhance the vibrancy and sharpness of the image.
