Character design workshop: guardians of Atlantis

Our group (Ryan, Charlie and I) were given the explanation for a character from the Victorian era in a steampunk setting and people from the lost city of Atlantis who are based on Roman and Greek culture but live under the sea.
I picked the second one and designed three:

 

The first one is nasty looking and more of a deep sea dweller, with a shield made out of a crab and big eyes to pick up the small amount of light that reaches the depths.

The second one is based on a Greek statue, with a technologically advanced shield.

The third one is a guardian with weapons for arms, as if designed to protect Atlantis.

 

My favourite is the first one so I painted it :)
