📝 About this app
Artists have always needed a quick and easy reference to help them understand the anatomy & forms of their portrait models. The Head Study App, is that resource.
These portrait models were created to make the study of portraiture easier, but also to enhance your knowledge of the human form. The appearance of the face can be understood best by studying what is underneath the surface. The simplified planar head and the skull in this app are made with the same proportion to make this comparison as clear as possible.
