i think Drawing is a visual art that is made using various instruments to make pictures on a page.Drawing is done by hand and can be anything your mind can imagine! the picture drawing is famous all over the world. so i think that is drawing.
I think that drawing is every kind of art that emphesizes on lines either monochromatic or in colors rather than on "patches" of paint and the relationship between the paint hues
