Thor the God of Thunder stands majestically at the entrance of Valhalla, draped in hyper-realistic, intricately detailed armor adorned with Nordic symbols. Mjölnir, his mighty hammer, is gripped firmly in his right hand, while vibrant lightning bolts dance and crackle around him, illuminating the grandeur of his presence. His piercing eyes convey wisdom and strength as he surveys the ethereal landscapes stretching beyond the golden gates. The skies behind him are a swirling tapestry of storm clouds and serene auroras, reflecting his dual nature of fierce warrior and protector.
