How I do Anatomy! (ft. Serenity :D)
1. grab a reference and start turning different parts of the body into shapes, I used circles but you can also use rectangles and triangles!
2. Connect the shapes
3. trace it into a messy sketch
4. add details (head, clothes, hair, etc.)
5. adjust it and change shape with lasso tool
6. Do line art! ( I decided not to I just colored instead)
I hope this helps! have a good day :)
