A GIF animation I made..

you still need improvement, as the neck is still too stout

I sketched a pose ref,



Some important things to note,

1- Neck should be proportional to the body. Usually, a neck will be 1/3 of the body width, not any more than that, save extreme stylization
2 - The head should connect to the back of the head, not the chin directly
3 - Forearm and arm both have the same length approximately, please give the joints more definition
4 - Breasts are sacks of fat, give it volume
5 - Learn shading. What you did is banding, it doesn't convey 3D well
