Architectural Vector Line-Art for Merch

I have a high-resolution reference photo of a building that I need transformed into a crisp, print-ready vector illustration suitable for merchandise such as curved shape mugs. The finished artwork should retain the key architectural forms and decorative motifs visible in the photo, rendered as clean, consistent line-art that scales perfectly at any size.

Here’s what I expect:

• A fully editable Adobe Illustrator (.AI) file, plus EPS and a transparent-background PNG.
• Line weights and detailing balanced for both screen printing and direct-to-garment methods, so the design looks sharp on cotton, ceramic, or any promotional surface.
• Colour kept to a minimum (single-colour preferred), unless you see a tasteful reason to add a limited palette that still reproduces well on fabric.
• Well-organised layers: main outlines, fills (if any), and decorative accents clearly separated.

I’ll provide the reference photo as soon as we start. Feel free to suggest subtle stylistic tweaks that enhance the clarity of the structure while staying faithful to the original architecture. If you have examples of similar vector line-art, I’d love to see them alongside your proposal.
