transform the input image into a soft hand drawn architectural illustration maintain the original composition and perspective but replace photorealistic details with clean ink linework and subtle pencil strokes use light watercolor washes with a muted pastel palette pale greens for trees and landscape warm beige and brick tones for buildings soft grey shadows simplified fa ades with suggested details rather than realism human figures as minimal white or lightly outlined silhouettes for scale only calm daylight almost no hard shadows overall look similar to an early design architectural sketch or competition illustration airy friendly and non photorealistic
