help in drawing dead tree?

i drew a dead tree for my art class, but i don't know what category it falls in with line and form. my drawing is quite bold there is no fading or shading, it has a line across the page that shows ground then the tree sits on top and at the bottom right corner there's a cross-hatched bush and then a barbed wired fence runs from behind the bush and across the rest of the page. really i just need a simple answer of what contour and gesture; line quality(creating variety and emphasis); line as value(using lines to create dark and light); and lost and found contour. thanks in advance :)
