if you don't mind me suggesting, if you want to fix the perspective, try angling her upper body so it gradually gets smaller, in a sense, so it looks farther away. if you go on the postion of the feet, keep the rest of the body in the same general direction (to help I'd suggest drawing two light lines on the widest part of the feet, extending off the page vertically to help line it up, then erase the two lines later) some body parts will overlap others.
The feet will hide part of the legs, the legs will hide part of the torso and bust, the bust will hide the neck. The head and sword will hide part of the arms. You want to make sure things look like they are being viewed from underneath, even angling the legs so you see some tush will help keep the angle. Perspective does indeed take a lot of practise, I was horrid at it when I first started out. Another trick I learned was when doing the lineart, make the lines thicker the closer it gets to your viewpoint. Anywho overall it's a very good pic ^^ Keep up the good work :3
