Have a look at this one:

This one consists of 8 frames. 1-front; 2-halfprofileR; 3-profileR; 4-halfbackprofileR; 5-back; 6,7,8 are just mirrored versions of 4,3,2. This was done just for fun as a test in gimp. Analyze the .gif file or I can send you the .xcf file so you can have a look at the process. If you really never have been doing cartoon animation I´d strongly recommend to get some books like "Preston Blair - Cartoon Animation" or "The Animator´s Survival Kit". There you get, at least, the theory and techniques used in 2d animation.
