I start to study realistic drawing from few months and the first problem that I have is to recognize the surface planes of the head, the front plane, side and the three quarter plane.
I tried to identify them on the Skull Photos and on the Head Pictures from every View by recognizing the light and shadow on the face, but I think it doesnot works!
I know that the Temporal Line identify the side plane of the head, but when the light doesn´t shows this temporal line clearly, how can you recognize it! Is there Anatomical Landmarks to recognize the temporal line in every view? also i couldnot recognize the part cheek part that should be included in every view on the front plane!
I also have a problem identifying the area under the jaw the ´´Suprahyoid Muscles´´ from the jaw line because the jawline in this picture is not sharp and clear! Does this underjaw part also appears in the front view?
