Edit image 1. Keep the composition, the cliff, the fish school, the comb jellies and the colours. Change only the light: the cliff and the sponges on the right are lit only very faintly by tiny blue bioluminescent sparks, as dim and soft as the rock in image 2, with smooth stylized surfaces and softer texture; the fish in the school get smaller natural eyes and their glow is only a neat row of separate small blue light dots along the belly; the comb jellies glow with soft faint blue bioluminescent lines.
