까마귀 날개 일러스트

Depict a single crow wing in an elegant natural-history study, feathers layered from glossy black primaries to soft charcoal down, angled diagonally across warm ivory paper. Combine precise ink contours with restrained watercolor washes, gentle cast shadows, visible paper grain, and a small botanical sense of balance. Keep the wing isolated and fully readable from tip to shoulder. No text, no watermark.
