This is the first image of my entry for the Artstation Challenge this year. It was a lot to design the environment and think about the functionality of this temple entrance in a swamp. For more work-in-progress please have a look here:

Story:
Long ago the dragon race was banished from the magical world. Dragons were once too powerful and greedy for all the peaceful creatures, which inhabited the world. Soon all kinds of dragons disappeared from the surface and were forgotten for centuries. Until a wizard heard the mysterious calling. Unable to resist the call, he sets out on a journey to find the tempting voice of a long-forgotten creature.
