My contribution to the "Beneath the waves" Artstation challenge.
The story line : Long after the end of mankind. Our sucessors, peaceful and industrous creatures who are living in the vast oceans, are collecting the remains of our extinct species. They explore the dead cities, looking for ancient artefacts. Their latest discovery, a nuclear submarine, might nevertheless be their last.
