"Create a series of conceptual sketches that illustrate the process of designing a futuristic architectural structure inspired by an airplane. Start with simple geometric shapes and gradually evolve the design into a detailed building with sharp, angular lines and aerodynamic elements. The sketches should show the integration of the structure into a natural wetland environment, featuring elements like water, tall grasses, and flamingos. The final sketch should emphasize the harmonious blend of advanced technology and nature."
