I'll try to briefly explain without getting too technical. Basically I begin by drawing the "keyframes" of a movement (the moments where one action begins and another ends, like the apex of a walk). Then I do the "inbetween" drawings. That involves a lot of tracing to make sure the shapes and sizes remain consistent, of course they aren't exact tracings since I need to make slight adjustments in order for the character to move. I hope this explanation helps you understand.

I'll check out your posts now. Cheers!
