At the top of the Illustration Style image, Happy 7th Birthday Nyla!

Hand-drawn, cute illustration with fine linework and textured brush strokes: in the center, a big smiling opal gemstone cabochon character with rosy cheeks and tiny dot eyes, wearing a tilted mini gold party crown. The opal’s play-of-color shimmers with swirls of mint, lavender, peach, pink, and sky-blue beneath a milky surface, dotted with twinkly star highlights.

The opal sits on a pastel cupcake with iridescent frosting; a sparkling number 7 candle burns with an opalescent flame. Two opal-drop balloons float left and right, and tiny opal butterflies flutter around. A gentle spiral of confetti, gold star sprinkles, and crystalline flower petals shaped like translucent opal shards wraps the scene, creating a balanced, celebratory composition.

Background: a warm, expressive watercolor wash from blush peach to buttery cream with subtle paper grain, soft vignette, and a cozy glow radiating from the opal. Fine ink linework, soft gouache textures, and delicate shading keep everything sweet and whimsical.

Lettering for the top line: playful hand-lettering with an opal gradient fill and subtle gold edge, lightly shadowed for readability.

Place a small, cheeky caption near the bottom on a tiny ribbon tag: ‘Hope your day is opal-tastic!’

Color palette: warm pastels (peach, blush pink, apricot, cream) accented with iridescent teals and lilacs, plus soft gold sparkles. Keep it cute, bright, and airy; no photographic realism. Full-page vertical composition with generous breathing room and crisp, high-resolution finish.
