Mystic Cavern
Open Entry (used assets from blendermarket.com like graswald and botaniq for the plants (some are edited) and textures from poliigon.com)
Made in Blender rendered in 2.83 alpha using the new adaptive sampling feature which is awesome.
Not 100% done yet but no time left after the render crashed like 17 times because of a compositing error.
Getting the water right was quite hard, as well as the lighting. I used some volumetrics, and HDR, multiple point lamps and a spotlight. The water was tricky as well. I used 3 layers (top, volume and color).
