Nét Vẽ Nguệch Ngoạc Màu Nước Tối Giản

Transform the reference photo into a charming minimalist hand-drawn doodle illustration. Preserve the main subject, pose, proportions, and overall composition while simplifying forms into playful, childlike shapes. Use loose brush-pen outlines with subtle wobble, uneven pressure, and naturally imperfect handmade strokes. Keep the linework clean, sparse, and expressive. Add delicate watercolor and ink touches with soft, restrained color accents, leaving abundant clean white paper space. Capture a naive sketchbook aesthetic with whimsical cartoon shapes, spontaneous marks, and gentle imperfections. Avoid realistic rendering, intricate details, heavy shading, or polished digital vector lines.
