Create a detailed illustration in black and white of a person surfing on a wave. The scene should depict the surfer in an action pose, riding a dynamic wave. The surfer should be balanced on the surfboard with a confident and focused expression, capturing the thrill of surfing. Include details such as the curvature of the wave, splashes of water, and the texture of the surfboard. Add elements like distant seagulls, a sandy beach in the background, and possibly other surfers or boats in the distance. The overall style should be realistic yet energetic, capturing the motion and excitement of surfing. The image should be suitable for coloring, with clear outlines and defined spaces. Use only black and white for this illustration. The dimensions should be 8.5 x 11 inches.
