Positive Prompt:
A masterful textured semi-realistic digital painting in a European graphic-novel style: a stern young woman teacher leaning against a wooden desk in front of a huge dark green chalkboard. She wears a dark navy double-breasted uniform dress with metal buttons and a belted waist, a matching peaked officer's cap with a gold insignia, and small rectangular glasses; her long blonde hair is woven into a single side braid, and her nails are painted dark. She stands at the right of the frame in three-quarter profile with arms crossed, head bowed in quiet contemplation. The chalkboard behind her is densely covered with handwritten chalk mathematics — trigonometric equations and inequalities — alongside sweeping blue chalk curves plotted over a numbered axis. On the wooden desk sit two vintage silver oscilloscope instruments with glowing green CRT screens, dials and buttons, a wire-mesh cup holding pencils, pens and scissors, and a small stack of hardcover books; a crumpled paper ball and a stick of chalk rest on the board's tray. Soft dim classroom light casts warm amber tones across the wood and wall, contrasting the cool green board and deep navy uniform. Muted painterly palette, highly detailed, refined finish.
Negative Prompt:
avoid: bright saturated colors, harsh flash lighting, modern laptops or flat-screen devices, glossy 3D render look, plastic skin, cartoonish chibi exaggeration, watermark, legible branding, extra limbs, malformed hands, bad anatomy
