fundamentals are less about anatomy and rules and more about what makes up a picture, like there are design elements, which consists of line, shape, form. value, space ect
then theres the principals of art which consists of, rhythm, balance, proportion, gradation, harmony, variety and movement ect
/ic/'s definition of fundamentals are anatomy, perspective, and anything hard ass technical that does not involve anything i mentioned above. and guess what so is your image. educate yourself, along with this stupid fucking board.
