At the top of the Illustration Style image, hand-letter the text Happy Birthday in warm, flowing script.

Hand-drawn illustration with fine linework, textured brush strokes, balanced composition, and a warm, expressive color palette. Scene: a golden-hour tennis court that gently blends into a science-and-robotics wonderland. Center-left, a friendly brushed-metal robot with soft teal LED eyes and a terry wristband lifts a graceful serve—tossing a softly glowing “atom” tennis ball with delicate electron orbits—while holding a classic wooden racquet subtly inlaid with circuit patterns. Center-right, a smiling scientist in relaxed tennis whites (lab coat neatly folded on the bench, goggles resting on their head) prepares to return the serve, posture open and kind. The net posts echo slender laboratory flasks; the court lines subtly resemble copper circuit traces. Around them, small cues of discovery: a beaker-shaped ball bucket, tiny micro-drone fireflies, and a chalkboard sky with faint hand-drawn constellations and orbital diagrams drifting like clouds. Use a warm palette of honey-gold, coral, soft teal, ultramarine, and cream; soft sunbeams, gentle vignetting, visible pencil-and-ink linework, and velvety gouache textures. Keep the mood sincere and heartfelt—shared joy, gentle smiles, and a sense of wonder. Compose with a calm diagonal from server to receiver, leaving generous sky space for the header.

At the bottom in small, handwritten lettering, add a single caption: Serving love at first byte.
