If her left left is supposed to be bent the way I THINK it is is, then she's some kind of contortionist. Her pose would make more sense if the left leg crossed the right, or if her hip was placed higher on her body.
That being said, I do like the way you drew the land around her. You have a good sense of color and direction, and I like how large she is compared to the trees.
I might work on anatomy if I were you, especially since it looks as if the sword is sticking into her ribs, and her chest is a bit unbalanced.
You have a good sense of shape, and I know you can do much better than this as an artist. There's just a few things you need to work on, as do we all. ^.^
