Bande dessinée / Storyboard - Cozy Witch and Halo Girl Study Scene

Create a detailed cozy anime illustration of exactly 2 cute fantasy girls studying in a bright white-background room, rendered in delicate ink lines, muted watercolor shading, soft gray-brown tones, and teal/purple accents. On the left, show {argument name="witch girl" default="a shy black-haired witch girl"} seated at a dark wooden writing desk, wearing an oversized black pointed witch hat decorated with tiny stars, buckles, purple flowers, chains, and ribbons; she has long wavy black hair in thick braids, pale skin, purple eyes, a black-and-white gothic dress with puffy sleeves, black stockings, and buckle shoes. She writes with a purple feather quill while resting her chin on one hand. On the right, show {argument name="halo girl" default="a cheerful silver-haired halo girl"} sitting curled up in a cushioned armchair, smiling with bright teal eyes, short messy silver hair, small teal hair clips, and a glowing blue-white halo above her head; she wears a futuristic white-and-black oversized hoodie with teal details, shorts, black socks, chunky white sneakers, and an ID-style tag, holding a clipboard and pen as if taking notes. Include a whimsical speech bubble above her containing exactly 1 small lightbulb icon. The study area should contain exactly 1 wooden desk, 1 wooden chair, 1 cushioned armchair, and 1 small round side table. On and around the desk include exactly 1 brass globe, 1 hanging lantern with a warm candle glow, 1 purple potion flask, 1 ink bottle, 1 feather quill, 1 closed black spellbook on the desk, scattered handwritten papers, and 1 stack of 3 dark books on the floor. Add wall details with exactly 2 pinned parchment notes and exactly 1 hanging trailing vine in a small wall frame. In the background, place exactly 1 low bookshelf holding several books, 1 geometric crystal orb, and 1 potted spiky plant. Near the right chair, include exactly 1 panda-faced backpack with teal eyes and bow, 1 small black round plush creature, exactly 1 open book on the floor, several loose pages, exactly 1 mug with a cute face on the side table, and exactly 1 potted leafy plant beside it. Use a charming slice-of-life magical academy mood, clean composition, soft shadows, lots of tiny decorative details, crisp character design, no text, no watermark, no photorealism.
