3D渲染金币福袋光环元素

A soft 3D red lucky bag in dopamine gradient colors (peach red to coral pink), with a round plump shape and a glossy rubbery surface. The opening is tied with a holographic laser ribbon that reflects rainbow colors. The bag is slightly open, overflowing with shiny gold coins inside, some coins have stars or sparkles on them. Surrounding the entire bag is a floating transparent rainbow-glass ring, made of iridescent translucent material with subtle reflection and prism effects. The ring is clearly on the outermost layer. The background is a soft dopamine color gradient, with smooth shadows and ambient lighting.
