Meet Groteus, the Grumpiest of Dwarves

Create a detailed and realistic character illustration of a large dwarf. He is clad in high-quality traveling and fighting attire, featuring a large cape with a drawn hood. The dwarf wields a formidable glass axe, its blade sheathed in leather, which also functions as a walking staff due to its size. His dark brown hair, tinged with light red hues, cascades along a well-kept long beard. His expression is stern yet friendly and wise, with piercing grey eyes that emit a multicolored glow reminiscent of an aurora, reflecting his primal arcane magic. The artwork should capture the essence of a powerful and mystical DND character, utilizing photography with dramatic lighting to enhance the magical aura emanating from his eyes and glass axe
