Just a quick peek from something I'm working on right now.
Never under-estimate the power of clear, strong silhouette. I think we should do everything we can to make it flow so as to maximize the appeal of a pose. I often work in silhouette when I'm polishing my poses. It's a great way to visualize things for readability- even something as simple and seemingly nebulous as a 'squash' shape on a fast inbetween is good to work out this way.
