Abstract Aqua Anime Poster

Create a vertical 2:3 abstract anime illustration on an almost white background with lots of negative space. Show a dynamic, partially cropped futuristic anime girl or character fragment in translucent aqua and teal linework, tilted diagonally from upper left to lower right, with flowing cyan hair-like strands on the left, a glossy triangular turquoise glass-like form extending to the right, and a small white angular collar or garment shape near the lower center. Add bright yellow paint splashes and loose calligraphic strokes bursting from the upper-left side of the head, with thin cyan swoosh lines arcing around the top and left edges. Place one large centered square overlay in front of the character, covering the face and torso; the square should have a soft pastel gradient from pale yellow-green at the upper left to mint and light cyan at the lower right, with clean sharp edges and no text. Use an airy high-key color palette of main_color, accent_color, white, and pale mint, with glossy highlights, sketchy anime line art, watercolor-like transparency, and energetic modern composition. Keep the image text-free, borderless, and poster-like.
