shape — defined by boundaries like line or color; can be freeform or organic
texture — can be tactile or visual; used to create contrast, emphasis, and to add detail to a design
form — three-dimensional, measured in height, width, and depth; in design, the shape of the object being designed or the illusion of form in print media
space — the area in and distance around objects in a design; in 3D designs, the area the object occupies
color — one of the building blocks of design; used for the focal point, subject, background, or to fill other elements such as line, shape, or typography
value — the range of light to dark in a design; helps create contrast, emphasis, and divide a space in both color and black-and-white design
typography — one of the most important elements of design; conveys information through text as well as the style and placement of text
I'm not sure how to elaborate on the rest, but I hope this helps in the meanwhile. To give you more aid, I attached a PDF I have on elements of art. Reading through it may give you more of an idea as to what to do.
