sorry but....
Sorry mate, but this really wasn't the greatest tutorial in the world. The decent way didn't look very good... He was leaning back and his legs were too far forward.(plus, If I wanna be picky, they were also moving too fast. And the half-assed way was at least quite well drawn...
And also, it offers no explanation of HOW to make the decent and the half assed way, because, well, all the bits where you explained them ran straight by 'cause you didn't put a stop action on them...
