How come my cartooning style is stiff and lifeless where as this is fluid and dynamic even though it's a still pose? I mean, I've done the whole "line of action" thing to establish the pose, but is there something else I'm missing?
1- You're starting to work with line of action, but you by no means have nailed it. Keep working at it until it's second nature. 2- Are you familiar with the principle of silhouetting? It goes hand in hand with line of action. 3- Are you using any other kind of construction?
I've been working on this project called "Sketckes on a Train" where I fill the pages of a sketchbook with illustrations based on what I'm feeling at the time. One if these days, I'm going to get around to scanning and posting them here.
