At the top of the Illustration Style image, Happy Birthday, Amy!

Hand-drawn, funny illustration with fine linework and textured brush strokes, balanced composition, and a warm, expressive palette accented with bold blues and teals. Scene: a gang of shaggy Highland cows barreling down a rolling Scottish singletrack on mountain bikes. Their horns poke through teal bike helmets, cowbells dangle as handlebar bells, and mud spatters arc in lively brush strokes. In the midground, a very serious “vet” cow in teal scrubs and a white coat, stethoscope around the neck, performs a bike check-up: listening to a squeaky wheel, clipboard in hoof. The vet bike has a teal first-aid pannier with a hoofprint cross; a tiny field “trail clinic” tent in matching teal sits on a hillock behind, flapping comically. One cow sports bandage-plasters on a tyre, another squeezes “grass gel” for energy. A trail sign shaped like a tongue depressor points downhill.

Color and mood: warm russets and caramels of the cows against a luminous blue/teal sky with painterly clouds; teal jerseys, helmets, and kit tie the scene together; pops of heather purple and mossy greens. Golden-hour light, soft shadows, playful motion lines, and a subtle paper-grain texture.

Small, cheeky extra text (keep it subtle): on the vet cow’s clipboard, hand-lettered in teal, “Diagnosis: udderly wheelie awesome!”

Leave generous sky space at the top for the greeting; keep the text small and the image dominant, energetic, and humorous.
