Colwyn from Krull With the Glaive on an Alien World

Create a cinematic poster in the style of Raphael Kirchner, Moebius, and Sergio Toppi, featuring Colwyn, the gallant hero from the 1983 film 'Krull'. He is depicted in his distinctive armor, brandishing the magical Glaive weapon, standing resolute against the alien landscape of planet Krull—showcasing stark, craggy terrains and looming castle structures. The scene captures an adventurous spirit, highlighting the hero's determination and the perilous beauty of Krull. Use hyperrealism with sharp, dynamic lines and a dramatic interplay of light and shadow, mimicking the high fantasy style of '80s movie posters. Output as a high-resolution digital painting, 16:9 aspect ratio, with vibrant colors and a cinematic composition.
