Guerriero corazzato semi-pixel

Create a vertical semi-pixel-art fantasy character illustration of {argument name="character name" default="a mysterious armored warrior"} standing front-facing in the center, full body, imposing and symmetrical. The warrior wears ornate polished {argument name="armor color" default="silver and white"} plate armor with gold filigree trim, layered pauldrons, gauntlets, greaves, a dark cape, and a horned wing-like helmet with a black visor and small glowing amber eyes. The hands are clasped over the pommel of a huge vertical greatsword planted point-down in front of the body; the sword has an elaborate crossguard and a blue jewel near the lower ornament. Add exactly one small cute {argument name="shoulder companion" default="hamster"} perched on the warrior’s right shoulder, creating a humorous contrast with the intimidating armor. Surround the figure with a tall ornate gothic frame made of curling gold metalwork and exactly four large silver feathered wing ornaments: two at the upper left and upper right, and two at the lower left and lower right. Place a decorative crest at the top center and another at the bottom center aligned with the sword. Background: a dark gothic cathedral or fantasy city interior with arched windows, towers, balconies, warm lantern lights, misty blue shadows, and deep navy-gray tones. Style: detailed 16-bit / semi-pixel challenge aesthetic, crisp pixel edges, high-detail sprite shading, dramatic metallic highlights, symmetrical composition, dark fantasy mood with elegant beauty, no text, no watermark. Use a vertical smartphone-like composition, {argument name="aspect ratio" default="9:16"}.
