Intercambio de rostro en retrato de grafito con preservación del estilo

use @img1 as the main base image for style, pose, lighting, composition and graphite drawing technique. Keep the exact side-profile portrait: woman with long dark hair partially covered by a textured headscarf, loose strands blowing, monochrome pencil shading, realistic hair detail and soft gradients on the neck and jawline. Replace ONLY the face area with the face from @img2 – the final result must show the SAME facial identity as @img2 , with identical facial features, profile and proportions, seamlessly drawn into @img1 in the same graphite style. Preserve @img1 headscarf shape, hair flow, neck, shoulders and all original shading and paper texture. Hyper-detailed pencil illustration, subtle tonal transitions, realistic yet artistic rendering. Negative Prompt: different face, wrong person, generic face, altered facial features, distorted proportions, mismatched shading, visible seams, digital smooth skin, low resolution, artifacts, changed headscarf, changed hair direction, flat contrast, different art style or composition
