Prompt: Produce a breathtaking, highly detailed fantasy artwork that encapsulates the essence of a formidable half-orc warrior in a world teeming with dungeons and dragons. This half-orc, a paragon of strength and valor, stands resolute before the ominous entrance of a long-forgotten underground labyrinth. His hair, a tangled mane, is meticulously gathered into an imposing, intricately braided topknot, hinting at his rich heritage and wisdom. His eyes, aglow with fierce determination, pierce the shadows that engulf the entrance, a testament to the indomitable spirit that drives him forward. Draped in a meticulously crafted suit of rugged chainmail armor, each link and rivet reflects the dim, eerie light emanating from the sputtering torches on the dungeon walls. The armor bears the scars of past battles, testaments to the countless perils he has faced and overcome. A weathered, tattered cape flutters behind him, hinting at the countless journeys he's undertaken. In his calloused, powerful hands, he wields an awe-inspiring two-handed battle axe, intricately adorned with tribal markings and runes that glow with ancient magic. The axe is honed to perfection, promising devastation to any dragon that dares challenge him. The ground trembles beneath his boots, which bear the weight of countless miles traversed in the pursuit of his quest.
