Deep Sea Civilization

Hidden away in the deep, unexplored corners of the ocean live the deep sea mer-people. They make shelter inside the network of tunnels carved into the mountains. The deep sea mer-people are fascinated by light and all things that glow, and maintain gardens of bioluminescent creatures on the sea-floor below their home.

Uni project, all the textures used are from CGTextures.
I'm hoping it's not too busy/chaotic looking, any feedback is welcomed. C:
