create an architectural rendering that preserves the exact geometry proportions and layout of the input model while transforming the visual style into a hand drawn architectural sketch use a loose expressive linework style with visible pencil and ink strokes lines should vary in weight and remain slightly imperfect to convey a hand drafted quality avoid overly clean or digital edges apply soft transparent watercolor washes over the drawing with selective color accents rather than full coverage keep most surfaces light and desaturated allowing the sketch lines to remain dominant introduce warm and cool tonal variation subtly muted reds greens and ochres to highlight furniture and key architectural elements lighting should be implied rather than fully rendered suggest daylight entering from windows with soft gradients and minimal shadow definition maintain a bright airy atmosphere with a white or lightly toned background include loosely sketched entourage people furniture d cor with minimal detail gestural rather than realistic to reinforce scale and liveliness without visual clutter textures should be suggested not photorealistic hint at materials like wood fabric and stone through light shading and line density rather than detailed mapping overall composition should feel like an early stage conceptual presentation drawing artistic atmospheric and slightly abstract similar to an architect s hand sketch enhanced with watercolor
