Naruto character anime illustration cool tone

Create a highly dramatic full-body anime character illustration, featuring , standing on a dark curved rooftop or giant pipe, facing forward, calm and focused, with blue eyes. He has his iconic spiky hair, wears a black forehead protector with a metal plate and spiral leaf symbol, and has three whisker-like marks on each cheek. The pose is set with one hand forming a vertical ninja hand seal in front of his mouth, the other arm crossing his body. He wears an orange ninja outfit, covered by a long black, tattered, wind-blown cloak with a high collar, loose black scarf ribbons flowing to the left, black boots, thighs wrapped in bandages; the upper sleeves are decorated with a circular red-orange spiral patch. The background uses a dark, low-saturation blue-gray, with no other scenery except atmospheric texture. Surrounding the character is 1 orange chakra-like spiral beam, and 8 orange leaves or ember fragments scattered in the air. Rendered in a hardcore high-contrast ink and gouache anime style: bold black brushstrokes, dry-brush edges, oil-paint-like orange highlights, deep shadows, color palette limited to charcoal black, soft navy blue, tan skin, and burnt orange. The composition is a vertical poster format, with the character slightly to the right, using a low-angle upward view, making the legs and cloak appear majestic. Add faint handwritten text in the upper left corner, and a subtle signature-like mark near the lower right corner.
