Reframe this concept as: surrounding the submarine are multiple small luminous yellow LEGO fish swimming at different depths, with several air bubbles rising upward in crisp detail. The seabed is made of LEGO bricks, including textured sand, blue tiles, and colorful coral elements in red, green, and yellow. The water is clear turquoise with gentle light rays filtering from above, creating lifelike underwater caustics and reflections. Shallow depth of field (f/1.8), powerful bokeh backdrop, 50mm lens, hyper-lifelike illumination, lively colors, high detail, polished professional macro photography aesthetic.
