This is concept work for my penguin idea. I started off with a basic outline, then decided the facial features were too big so shrank them, then it still didn't look quite right to me, so I referred to a photo of a actual penguin and realized the facial features were far too central so I spread them out to the sides of the penguin's head as the penguin has a beak extruding from the center of it's face.

I'm really pleased with the final penguin. I think it looks really suited to the voice I'm putting it too and well stylized.
