Hang in there! Keep practicing and experimenting. I know for myself there was a long period at first where I just could not get the poses I wanted. Then one day I hit on an idea to stand just like the default pose and then move myself into the position I wanted to pose. I did it one move at a time and then made the same move for my posed character. I think I would have died of embarrasment if my wife had come home early and found me standing like that, moving one arm, then tapping at the computer, then repeating this until I was sitting in the sofa... but hey, it worked. Another big thing for me was when I realized that the motion is not necessarily the movement. By this I mean, you turn your head to the right - that's the motion. But the movement (for your character) is -not- to click on the head and set twist to '23'. The movement is more like lower neck twist 7, neck twist 10, head twist 6. Well, this is just my .02 worth. Hang in there and keep trying. For myself I know there was a frustrating 'hill' to get over.
