At the top of the Illustration Style image, "Happy Birthday"

Hand-drawn illustration with fine linework and textured brush strokes, balanced composition, and a warm, expressive color palette (coral, peach, mustard, teal, plum) on a subtle paper-grain background. Scene: a lively dance-workout party in a gym turned disco. Center stage, a joyful character in retro sweatband, legwarmers, and trainers breaks into a dance move while doing light curls with a tiny cupcake-shaped dumbbell. Around them, friends in playful workout gear perform synchronized dance steps—grapevines, high-knees, jazz hands—while jump ropes swirl like ribbons. A glittering disco ball hangs overhead casting warm spotlights; confetti and streamers drift through the air. Visual gags: a barbell loaded with donut-shaped weights, kettlebells wearing party hats, a yoga mat doubling as a mini dance floor, and a weight bench holding a birthday cake with glowing candles. Composition: centered focal character, friends flanking both sides to frame the scene, props forming an arc that guides the eye upward to the “Happy Birthday” text; soft shadows and dynamic motion lines for energy. Keep the image large and character-led, with generous breathing room.

Add a small hand-lettered caption near the bottom: "Cardio? I thought you said party-o!"
