A highly detailed hand-drawn illustration of a field pattern featuring pumpkins, hay blocks, and corn plants. The pattern should include pumpkins in different sizes and stages of growth, hay blocks with intricate natural details, and corn plants with visible kernels and husks. The drawing should be in a rustic style, using very long strokes without lifting the pencil, creating a continuous flow. The background should be white. Ensure the illustration captures the natural details and textures of the pumpkins, hay blocks, and corn plants, making them appear realistic and textured. The overall style should be simple yet detailed, with an organic and natural feel.
