I took my inspiration from Andrew Loomis - Figure Drawing For All It's Worth. There's actually a possibility for free download of this book at http://illustrationage.com/2013/04/02/free-andrew-loomis-art-instruction-downloads/ . When you use these human frames it's easy to get the figure's actions look right very fast. You quickly know what posture works and what doesn't. Now I quess I should just draw more.
