Create a hyper-detailed pencil and charcoal sketch of a majestic lion, utilizing intricate line art to convey a dreamy atmosphere. The lion should be depicted in a regal pose, with its flowing mane rendered in delicate, swirling lines that suggest movement and grace. Surround the lion with nature motifs, such as stylized leaves and abstract representations of the savannah, creating a harmonious blend of wildlife and environment. The overall mood should be dreamy, with soft shading techniques that simulate light and shadow, enhancing the ethereal quality of the composition. Ensure that the sketch is highly detailed, capturing the texture of the lion's fur and the expressive features of its face. The final artwork should be digitized in 8K resolution (7680 x 4320 pixels), ensuring every line and detail is crisp and clear. In post-production, include contrast adjustments to emphasize the depth of the sketch while maintaining its delicate nature, resulting in a stunning visual representation of this majestic creature.
