Facial Expressions

I initially wanted the character to have no mouth, but seeing as his eyes would not be visible, I felt this would limit the amount of emotion I could convey. I decided to give him a small mouth, and with the eyebrows I felt this would be enough to give him some form of personality. The character Wall-E had no mouth, and yet was able to convey a wide range of emotions just from his binocular-like eyes. I hope to be able to do the same with my character through his mouth and eyebrows.
