I think the pose looks rather awkward. I think it would look better if she was facing the direction she's leaping or flying. It also looks like she's resting on something the way her bent leg is angled, like on a bed and with her hand on her hip. She also looks a bit skinny for a super heroine, I think.

I tried something different with the arm above her head, but now it just looks like she's running, so maybe just stretch it out more where it is or something. I think she just looks too relaxed in my attempt, but maybe you can find some use in it.
