At the top of the Illustration Style image, Happy birthday Mum!

- Scene: A cozy living-room “Mum Detective Coffee Club” meet-up turned playful mystery. A round coffee table dominates the center, covered by an oversized hand-drawn Sudoku grid like a detective board. Red yarn connects certain numbers like a conspiracy diagram, and sticky notes frame clues.
- Cats: Three cheeky feline “detectives” run the show—one in a tiny trench coat peering through a magnifying glass at the Sudoku, one tangled in the red yarn like fake “caution tape,” and one perched atop a stack of thriller novels wearing reading glasses, tail flicking with authority.
- Mums: A few relaxed mums in comfy cardigans and messy buns, gathered with steaming mugs, sharing a laugh. One holds a thriller novel upside down, another leans in delightedly as the cats “investigate.” Keep faces friendly and expressive, not overly detailed.
- Coffee details: Rich mugs of coffee with steam curling into question marks, a saucer dusted like a “fingerprint” in cocoa, biscuit crumbs arranged like clues on a napkin.
- Thriller touches: Soft venetian-blind shadows across the scene, a desk lamp casting noir-ish light, yarn crisscrossing like evidence tape, pawprints stamped near the Sudoku “crime grid.”
- Extra text in-scene (single short line): A bright yellow sticky note pinned to the Sudoku board reading: “Whodoku?!”
- Title treatment: Hand-letter the top line in playful, confident script; let the exclamation mark curl into a cat’s tail for a witty flourish.
- Style: Hand-drawn illustration with fine linework, textured brush strokes, balanced composition; warm, expressive palette of terracotta, mustard, teal, soft cream, and inky navy lines; subtle paper grain.
- Lighting and mood: Sunlit, cozy, and funny—domestic chaos meets light-hearted thriller.
- Avoid: Real logos/titles on the books, additional text beyond the header and “Whodoku?!”, any dark or scary elements.
