Kawaii Emotion Explosion Collage

Goal: Create a hyper-colorful anime “emotion explosion collage” poster for {argument name="character name" default="Milk Signal"}, featuring one large central chibi/anime girl surrounded by exactly 18 smaller reaction cutouts and pop-up UI stickers.

Canvas: Square 1:1 composition, bright yellow doodle-filled background, dense sticker-bomb layout, no empty space. Use thick white sticker outlines, black drop shadows, neon pink/cyan/purple accents, glossy highlights, energetic Japanese kawaii magazine style.

Main subject: A cute blonde anime girl with a short bob haircut and bangs, large lavender-purple eyes, pale skin, flushed cheeks, teary embarrassed expression, sweat drops, open trembling mouth, and both fists held near her collar. She wears an oversized pale blue sweater over a frilly white blouse, with small earrings. Place her huge in the center, cropped at the torso, as the emotional focal point.

Surrounding reaction cutouts: Add exactly 18 small chibi versions of the same blonde girl around the edges, each with a white sticker border. Include these 18 expressions/actions: 1 smiling with eyes closed and hands near cheeks, 2 blank worried face, 3 shocked with open mouth, 4 excited laughing pose, 5 surprised with round eyes, 6 crying into sleeves, 7 timid blushing, 8 embarrassed hiding hands at mouth, 9 panicked tiny full-body pose, 10 teary pleading face, 11 angry pout with red stress mark, 12 sleepy bored face, 13 winking smile, 14 heart-eyes love expression, 15 unimpressed side-eye, 16 cheerful open-mouth smile, 17 confused looking sideways, 18 small surprised face at bottom edge.

Sticker and UI elements: Include exactly 5 retro computer-style pop-up windows with readable text: “ERROR” in pink at upper left, “Sending...” in Japanese as 「送信中…」 near the top center, “LOADING” at mid-right, “CONNECT” at lower-left, and one small magenta heart window near upper-left. Add exactly 4 speech bubbles/symbol bubbles: “!!!” at upper-right, “???” at upper-left, “?!” near upper-right-middle, and a three-dot bubble at lower-right. Fill the rest with neon stars, hearts, lightning bolts, music notes, arrows, pixel invader icons, squiggles, tiny sparkles, and waveform doodles.

Title typography: Large bold Japanese bubble-letter logo across the lower center reading {argument name="main title text" default="ミルキュン シグナル!"}. Make the lettering glossy and layered: hot pink top line, cyan/turquoise lower line, thick white outline, dark navy shadow, yellow highlights, small heart icon beside the title, rainbow swirls behind it, and a dynamic sticker-like 3D effect.

Visual style: High-energy moe anime illustration, polished digital art, pastel blonde hair, glossy eyes, exaggerated emotional expressions, sticker collage, saturated candy colors, clean line art, sharp details, playful chaotic layout, social-media-ready Japanese pop aesthetic.

Constraints: Keep the central character dominant and clearly visible, preserve the exact count of 18 small reaction cutouts, 5 UI windows, and 4 speech bubbles, avoid realistic rendering, avoid muted colors, avoid extra large text beyond the title and UI labels.
