Act as a fantasy illustrator with 10 years of experience in mythical creature design. Create a highly detailed digital painting of a majestic griffin soaring over a jagged mountain peak at sunset. The griffin should have [golden eagle wings], [lion's body with a shimmering bronze mane], and [piercing emerald-green eyes]. The mountain peak should be covered in [ancient runes carved into the stone], surrounded by [swirling mist], and bathed in the warm glow of the setting sun. Include subtle magical effects like [sparks trailing from the griffin's wingtips] to emphasize its mythical nature. The composition should be dynamic, with the griffin in mid-flight, wings fully spread, conveying power and grace.
