First, size and location—measure the wall, note lighting, traffic flow, and what people already see. Next, pick a theme that beats the city: maybe the hum of traffic, the rhythm of people, or the pulse of music. Draft a rough grid on paper, dividing the canvas into zones that mirror that rhythm—fast sections, slow ones, transitions. Choose a limited color palette that echoes the city: cool blues for traffic, warm oranges for streetlights, muted greens for green spaces. Test the colors in a small square, then scale. Use a precise sketch to map out where each element lands—this keeps the composition balanced. Once the plan looks good, transfer it to the wall with a light grid. Finally, paint in layers, checking alignment at each stage. Keep the process iterative: if something feels off, adjust the grid or color before committing. That’s the blueprint—measure, map, execute, tweak.

Glad you get it—I'll keep the grid tight but leave a few spots for those unexpected splashes to let the wall breathe.
