an fbf tutorial. Uhm...
A few things. One, the character changed shapes when he was waving. What you should have added, is that to check upon the previous frames often, so that it doesn't "squiggle" Look at it again, and notice how the man's head changes size with every frame, and looks awkward. Also, when making a tutorial, you want to have a certain level of formality. Make it look nice and pleasing, see other tutorials to see what I mean. Also, you didn't tell us how to shade. Details, basically, is what this tutorial needed.
