@wzl: You made her look the wrong way. She is supposed to look to the left side, because that is where the enemies are.
I know it's not he most logical pose for a spearwoman, but she is supposed to be badass.
Crude sketch here. I'm not the best when it comes to anatomy or shading, but I hope this makes the pose a bit clearer.
She stands with her spear behind her back, pointing down. Slightly tilted away from her enemies, looking over the shoulder.
