A vibrant surreal pop-art composition featuring oversized cannabis leaves, symbols, and whimsical, dreamlike motifs. Use bold neon colors—electric greens, hot pinks, electric blues, and sunny yellows—with thick black outlines and high-contrast shading. Incorporate abstract shapes, swirls, stars, and confetti-like particles that float around the leaves. Create a cosmic, gradient background that shifts from deep greens to purples and blues, giving a psychedelic feel. Frame the scene with a large, semi-transparent dark gradient rectangle in the center to resemble a poster overlay, while leaves and symbols peek around its edges in a dynamic, graphic style. Overall mood: playful, trippy, and vividly psychedelic with a glossy, poster-art finish.
