Art style: Dark Fantasy.
Full-length view, the entire figure visible from head to feet, standing upright — a majestic elder dragon of colossal size, noble and wise. His body is covered in overlapping deep emerald and slate-grey scales with faint bronze edging, weathered and scarred from age. Enormous leathery wings arch high behind him, semi-translucent membranes stretched over long ribbed struts. A broad noble head crowned with sweeping backswept horns and a fringe of grey spines, deep amber eyes calm and knowing, a long silver-touched beard-like whisker under a strong angular jaw. Powerful muscular limbs end in four thick clawed feet planted firmly on rocky ground. A long tail with a spade tip curls beside him. He stands proudly at the edge of a misty ancient volcano at night, tail resting on dark stone, faint warm embers drifting nearby.

FINAL STYLE ENFORCEMENT (this is the authoritative rendering directive — it overrides any style wording elsewhere in the prompt):
Render this image entirely in "Dark Fantasy" style. Match the lighting grammar, material response, colour science, level of realism / stylisation, line weight, and shading model typical of "Dark Fantasy". Keep the subject, composition, camera angle, lighting direction, and colour palette from the description above — but EVERY surface, skin, fabric, material, and environmental element must be rendered in the "Dark Fantasy" idiom, not in any other medium.
