A hyper-realistic depiction of Thor, the God of Thunder, adorned in extraordinarily detailed armor rich with intricate Norse symbols, gripping Mjölnir firmly in his right hand. Lightning arcs and crackles around his form, illuminating the scene with a brilliant electric blue hue. He stands majestically at the grand entrance of Valhalla, the golden-hued hall of the honored slain. A backdrop of towering, ornate doors engraved with epic tales and runes serves as a gateway to the legendary realm. The atmosphere is charged, as if the very air hums with anticipation, echoing the reverence and power of the scene.
