Good work man...that's mint. You should put a little legend at the address positions.
i.e. yellow=shoulders
black=left arm
red=right arm
I figured it out after looking at the next few slides but looked at it crosseyed for a bit...the impact fix one looked weird at first (when I didn't understand what the lines were).
That's just nitpicking tho...really is good stuff man...a picture is worth 1000 words.
I like the way the hitting and swinging stickmen demonstrate the different plane angles of the hitter and swinger.
