A hyper-realistic close-up of a slice of vibrant yellow lemon cheesecake, with a smooth, creamy lemon-flavored filling set atop a buttery, golden-brown crust. Inside the cheesecake, there's a thick layer of rich blueberry jam, filled with fresh blueberries, creating a contrast of purple and yellow. The top of the cheesecake is elegantly garnished with more fresh blueberries and a delicate drizzle of blueberry syrup that gently cascades down the slice. A couple of fresh blueberries rest casually next to the cheesecake. The background is simple and neutral, ensuring the focus remains on the bright yellow cheesecake, the deep purple blueberry jam inside, and the fresh, juicy berries.
