Surreal pastel walkway through whimsical geometric houses

surreal childlike architectural illustration of a winding pastel blue walkway curving upward through a series of whimsical multicolored geometric houses, each house with randomly placed windows and doors, outlined with black pencil sketch lines, bright pastel color blocks like yellow, pink, mint, and orange fill in the abstract forms, floating cotton-like clouds in soft cyan and pink hover in the scene, tiny scattered shapes and squiggles fill the white background like hand-drawn symbols, staircase has light shading and curved dimension, flat lighting with no shadow, style resembles sketchbook art with colored pencil and watercolor overlay, ultra detailed, not photorealistic
