Creature Design - Arctic Scene

For our game I am one of the artists and to start with I need to come up with some creatures or enemies that might either simply populate the levels or be obstacles you must avoid in order to prevent them from slowing you down. As our game revolves around the arctic I decided to design some creatures for the underwater scene we are implementing into our game. Michael is covering the main character and OB is doing some land animals so I think me covering the underwater scene is a good idea. The first thing that came to mind is a seal. I will have a go at trying to draw a character based around this. I will experiment slightly with mutation to as the game is designed in a new era, penguins fly! Stay tuned!
