Final answer:
The Kamakura-era portrait of Daruma is characterized by broad brush strokes, limited ink usage on facial features for a mystical look, and a contrast between the well-defined body and the abstracted face.
Step-by-step explanation:
The portrait of Daruma in the Kamakura-era art is distinguished by several visual hallmarks typical of the period. One of these hallmarks includes the use of broad brush strokes to construct the shoulders and the body of the figure, while the facial features are finely detailed, creating a sense of depth and character in the image. Additionally, the relatively limited use of ink on the face suggests a more mystical and contemplative appearance, allowing the details to recede into the background and giving the subject a somewhat abstracted, but still personal quality that is reflective of the Kamakura aesthetic. This manner of representation creates a dynamic contrast between the boldly defined body and the ethereal visage of Daruma, embodying the period's stylistic shift towards a more subjective and expressive approach to religious iconography.
