Create a surreal and intricate illustration in the style of Antonio Gaudi, inspired by the theme 'Time is the most valuable thing we possess.' The image should emphasize the irreplaceable nature of time and its fleeting essence. Incorporate organic, flowing forms and mosaic-like patterns characteristic of Gaudi's architecture. Use vivid colors and elaborate details to depict the preciousness of each moment. The composition should evoke a sense of wonder and contemplation, reminding viewers to cherish every second and use their time wisely. Elements of nature, such as trees and flowers, can be intertwined with abstract clocks and hourglasses, symbolizing the connection between time and life. Let the artwork convey a message of appreciation and the importance of valuing the present. The image is hyper-detailed, in 4K resolution, with high focus and sharp details.
