Apply realistic anime rendering to the actual selected accepted source image as a style-only edit.

Preserve each original subject's accepted visible form, including any established partial transformation, and existing body geometry exactly: the same overall silhouette, body proportions, breast size and shape where visible, chest-to-torso relationships, shoulder width, waist, hips, and limb thickness. Retain the original pose, camera angle, perspective, crop, subject scale, clothing or nudity state, garment fit and support, background layout, and lighting setup and illumination.

Change only the rendering treatment to realistic anime illustration, restrained anime stylization, naturalistic tonal modeling, subtle surface texture, lifelike material response, fine integrated contour accents, selective crisp detail, coherent depth and perspective, natural color.

Apply shading and texture to the existing forms. Use the source image's existing breast size at whatever size is already present. Preserve the source's current physique and surface materials instead of reconstructing them from a generic character template or a superseded canonical form. Keep changed and unchanged regions attached to their original subject. Keep hidden and out-of-frame areas as they are.
