A real photograph of clouds as the base image, with a hand-drawn illustration overlay added on top. Simple black ink doodle lines are drawn over the clouds, turning them into cute [dog] characters. Naive, childlike illustration style, round eyes, minimal facial features, playful proportions. The drawing feels like it was sketched directly onto the photo, not painted or rendered. Strong contrast between realistic clouds and simple illustration lines. Note that the shape of the graffiti should closely match the outline of the clouds.
