Otherworld Main Character Concepts

This are the preliminary concepts and sketches I did for our Otherworld project's main character.  We wanted the character to suit the look of a scientist who has crash landed on an alien planet and must survive its inhabitants, set in a futuristic setting.  The scientist has a wrist mounted interface that he uses to scan the environment and keep track of his progress through the world map and the creatures he encounters.  The concept revolved around the player having to use the environment to their advantage to escape and hostile creatures rather than equiping them with an assortment of weapons.
