Anna's Witch Queen Sketches

Hey gang! Sorry for the late night post, I'm on a weird schedule. So here's where I'm at for now. I tried to fix the problems, but let me know if I missed something or a new problem popped up!
I'm still not totally solid on a hairstyle. Any that you love? I know I could push the facial expressions further, I was just getting used to the features.
Also not head over heels for the pose. And what do you guys think about the slit in the dress? The bottom of the dress was rushed, I'll make it more smokey and wispy.
Any input would help, of course. Thanks guys!
