Enchanted Ring Over a Luminous Elven City

Cartoon-style illustration of an enchanted ring glowing with emerald light, resting in the foreground on a polished silver pedestal or held in a gloved hand. The ring has a gold band with ornate filigree and a central gemstone that refracts light into twinkling particles, with runes etched along the band. Behind it, an elven city rises among living trees: tall slender towers of crystal and gold, curved ivy-covered bridges, and glowing levitating lanterns. The city glows in teal, gold, and jade hues under a twilight sky, with soft pinks and purples adding whimsy. The art style is bright and friendly with bold outlines and smooth cel-shading; the composition places the ring as the focal point in the foreground while the city blurs softly in the distance. Camera angle slightly from above; air filled with motes of light and tiny sprite-like figures weaving through arches. The mood is magical, adventurous, and whimsical.
