You might want to restart completely and try to use a stick figure rather than blocks as a base. Your current base lacks a neck and the limbs don't make sense. I think that experimenting with a stick figure until you find a good stance / pose is much easier.
Here's a little sketch of mine to show what I mean. It's far from perfect (I'm not that good at making special poses myself), but you should get the idea.
