This is my submission for the "Under the sea" skin contest, it took me a little while to get the shading right but I like the end result of this.
Description:This is a Neptune knight, the creature is from deep underwater.

From living underwater so long, the creatures evolved into intelligent beings due to their being seperate from humans.
They developed their own technology and their own soldiers, this is one such soldier.

When the dead body of one was discovered by humans founding a village they were dubbed "Neptune Knights"
due to living in cities built far underwater.
