In a dazzlingly abstract birthday scene that seems to whirl with energy, Harry Potter and Spider-Man are ensconced in a vibrant, kaleidoscopic world of shapes and colors. Picture a background inspired by Kandinsky's love for vivid, swirling forms and Mondrian's structured grids, forming a dynamic backdrop of floating geometric shapes in primary colors interspersed with splashes of neon. At the forefront, Harry Potter stands poised with a microphone shaped like a lightning bolt, wearing an outfit that combines his iconic Gryffindor robe with a jazzy, sequined cape reminiscent of De Kooning's expressive brushstrokes. He's mid-karaoke, his mouth open wide in song, captured mid-note, with a whimsical thought bubble above his head saying "HAPPY BIRTHDAY GEORGE" in quirky, handwritten font echoing Cy Twombly's scrawling style.

Next to him, Spider-Man is striking a playful pose, one hand thrown up in the air as if he's caught in the euphoria of a rock concert. His suit appears to be splattered with Pollock-esque drips and splashes, each paint streak resembling a vibrant, action-packed motion line as though he's just swung into the scene. Around their feet, Rothko-inspired blocks of color form a stage-like platform, and balloons shaped like floating, abstract orbs by Miró hover in the background, casting faint shadows that add depth to the composition. Amidst this joyful chaos, intricate details like tiny, magical fireworks and webs of shimmering spider silk crisscross the card, forming subtle patterns that are almost maze-like, drawing the viewer in deeper into this fantastical birthday celebration.
