黒板チョーク画スタイル AI プロンプト - 手描き風変換

I uploaded a photo. Please re-render the scene as a hand-drawn chalk illustration on a dark green classroom blackboard. Use white chalk for main outlines and pastel chalk colors (light pink, light blue, light yellow, light green) for accents and color blocks. Visible chalk texture with slight smudges and dust, dark green blackboard background with subtle horizontal eraser streaks. Preserve the person's identity, face shape, hair length, hair color, and outfit silhouette so the chalk drawing remains clearly recognizable. Loose hand-drawn line quality, not vector-perfect. Output at the original resolution. Hand-drawn chalk illustration style. Do not over-render with realistic shading or photographic detail — keep the loose chalk-sketch feel, and no realistic skin tones.
