Vividly colored image of Gandalf, a wizard from the Lord of the Rings. He is depicted in a three-quarter view, walking and carrying a staff. He is wearing a long flowing robe and a pointed hat. His beard and hair are long and flowing. He has a stern but benevolent expression. The linework is somewhat loose and expressive, hyperrealistic style. A medieval, fantasy setting.The background is faintly colored. Include detailed rendering of the folds of his robe and the textures of his beard and hat, along with the staff. The attire should resemble a medieval style fantasy costume with a focus on the textures and details of fabric and material. Emphasize the strong lines and shadows of the sketch, while still maintaining a clear and compelling image. Preserve the style of linework and shading from the original sketch.
