This is the design process for the Destroyer, the lead villain of Mythic Realms! I knew I wanted him to have a very classic fantasy RPG villain look to him, since the game's style is a bit of an homage to that stuff.
These NPCs are the core cast of the game, who give you quest and drive the story forward. I had the pleasure of designing this cast, and went through several iterations of silhouette designs before landing on their final look.
