Hi there! Really loving her design - you should keep at it! Very nice work and detailing!
However, I feel like the pose is a bit stiff. Maybe it's just me.
Is she swinging the blade there, or just holding it up? The lines around the blade suggest there is movement but the rest of her body says "I'm standing still." In the first case, I'd suggest maybe giving a bit more movement to her lower body. A wider stance, perhaps, to balance the upper body movement!
