Create a hand-drawn sketch illustrating three tangible parameters for an underwater habitat design. The sketch should depict: Topography of the Ocean Floor – showing the varied contours and depth levels of the seabed, with textured shading to indicate different elevations. Modular Growth – illustrating a series of interconnected pods expanding organically, similar to coral formations, to show how the habitat can grow and evolve. Pod Connection – highlighting the linking mechanism between the pods, with flexible pathways and structural connections resembling octopus tentacles. The drawing should be in black and white, with fine line work, cross-hatching for shading, and annotations to emphasize key elements.
