Warning: I am not good drawing humanoid figures. So please understand I may have made some mistakes drawing the human anatomy. I am learning.
I originally planned to do a young teen wolf anthro bjd so I did make a working drawing. For her proportions I found a drawing of a chibi unicorn (below picture on left) I liked. Although I like the body proportion, I do not consider the enlarged head visually appealing for my doll. So I made an assumption on how big the head will be and drew my anthro (below picture on right), which is 5.5 heads.
Later while searching for other bjd designs I came across some working drawings (picture below) with 4.5 head, 5 head, and 5.5 head proportions. I can see some changes I want to make when comparing my anthro with the 5.5 head drawing.
At first I was planning on keeping the 5.5 head proportion, but later decided to make changes. I wanted her to look younger and more child like. So I drew a 5 head design(below picture left drawing) to see how she would look. But I wasn't satisfied yet, so I decided to draw a 4 head design (below picture right drawings).
Now that is much better. I guess the above picture could qualify as a working drawing, but I want to refine it some more before considering the design process completed and start working with clay. Also I want to consider range of motion, joints, etc.
