This is the base female form I draw my people with. It uses circles, trapezoids, and ovals. The proportions and other important feature parts are marked by lines such as Jean level, collar bone level, eye level, mouth level, nose level, hairline, etc. Experience got me using this form over time as I developed different conclusions about the human shape and I am very proud of this reference sheet I drew for my personal form. Weight and build can be adjusted as necessary.  Shes wearing a tank top and shorts. I didn't erase anything i drew on this, so if i ever needed a reference i could see all the shapes used to form it.

Anyway! Not sure if i mentioned this before but if you want me to draw anything for you just ask! I'll do my best!
