Create a realistic 3D model of a blooming cactus. The cactus should have a thick, ribbed green body with realistic spines distributed along its vertical ridges. On the top or sides, include one or several large, fully open flowers in bright colors such as pink, red, or yellow. The petals should be delicate, slightly translucent, and vivid, with visible texture. The cactus should sit in a simple clay or stone pot with sandy soil. Add small details like surface dust, subtle imperfections on the skin, and light shadows from the spines. Use soft natural lighting to enhance the contrast between the rough cactus skin and the soft petals. The model should express the beauty of resilience, combining harsh desert texture with gentle floral elements.
