Illustrate an urban landscape during a gentle rain, capturing the reflections and lights of a bustling cityscape. The watercolor painting should focus on capturing the movement and life of the city – bustling people under colorful umbrellas, blurred reflections of neon lights in small puddles, and the facades of tall buildings melting into the grey sky. The rain should create a wash effect where colors bleed into one another, suggesting movement and flow. Include a vintage streetcar or bus, its vibrant paint softened into muted tones by rain, adding nostalgia to the scene. Surround the cityscape with soft edges, as if viewed through a window streaked with rain, enhancing that quintessential watercolor blur that evokes both the energy of the city and the softness of the rain.
