Its quite impressive, you picked a challenging perspective. the main part of your image that stands out is the face, I've tried to illustrate what I mean by drawing a red pizza box. because while you did the body really well, the head got a little squished. the simplest fix is to add depth to the face, hide the furthest eye behind the nose, but that doesn't fit the style your going for so I also drew a little spherical head to give an idea of the depth missing. and lastly I showed an alternative option which will be easier to experiment with. another option is to make the eye narrower and bring the hair further out the back. this will make the head deeper. hope this helps
