[Lighting: natural]
Art style: Modern 3D Animation.
Rexley stands at the very front of the speeding mine cart, his hooves on the edge, head held high in a 'heroic' pose. The cart is currently mid-air, having just hit a jump where the tracks have ended. The background is a vast, dark underground cavern. The lighting comes from the glowing mushrooms on the cave walls. The colors are neon greens, deep teals, and dark shadows.

FINAL STYLE ENFORCEMENT (this is the authoritative rendering directive — it overrides any style wording elsewhere in the prompt):
Render this image entirely in "Modern 3D Animation" style. Match the lighting grammar, material response, colour science, level of realism / stylisation, line weight, and shading model typical of "Modern 3D Animation". 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 "Modern 3D Animation" idiom, not in any other medium.
