New Sketch...help

Yilan

So I recently drew this and I need help. I can never get the head proportionate or the right size when I draw the body first. Any tips? Also, what do u guys think of the body, I think it’s pretty good (I wish my curves were that nice😝) but I’m open to any tips as well. Thanks!!

Update: I fixed it up a bit, not a huge difference, but it looks a little better.
