>>1882219Hands, fucking hands are always a sticking point in illustration. One exercise one ofmy teacher had us do one time was practice drawing hand like things with and without hands in them. Namely gloves and stuff. Don't get lazy with your hands though. Even doing things poorly is beter then getting stuck in a lazy rut.
Maybe for your hair try making a sort of flow guide for yourself first. Draw her head bald first, pick a few key spots on the scalp, and draw a single line flowing down as a single stand of hair. Then, you can follow that movement when using standard hair drawing styles and techniques.
