Red Thread of Fate String Art

Transform this portrait into a string art representation. The person's face and features should be created entirely from taut red threads stretched between small nails or pins driven into a white wooden board. The threads should create the portrait through density: areas with many overlapping threads appear darker (shadows), and areas with fewer threads appear lighter (highlights). The individual red threads should be clearly visible, each one a straight line between two pin points. Show the small metallic nail heads glinting at the perimeter. The board should have a slight wood grain texture. Light should cast subtle shadows from the raised threads onto the white board behind them. The effect should be recognizably a portrait made entirely from the red thread of fate (赤い糸).
