Immerse your canvas in the surreal fusion of "Dune's" desert planet and the mystique of "Moby-Dick." Picture a vast, sandy sea stretching beneath a scorching sun. In this desolate expanse, conjure a colossal sand whale breaching from the dunes, a creature of both beauty and menace. Beside it, a lone man, clad in attire blending futuristic and seafaring elements, stands with determined awe. Let the swirling sands form intricate patterns around this ethereal duo, merging the cosmic vastness of the desert with the maritime allure of the great white whale. Craft an illustration that captures the epic essence of adventure in a desert ocean teeming with mythical wonder.
