Because you can express your felling onto it pls mark me braliest
sketches and paintings are both forms of artwork done by the artist.
they are quite diffrent though sketchs are a rough draft of a peice of work.
paintings are artwork done with paint brushs and diffrent technic's, they could be vividly colorful or black in white its up to the artist.
hope this helps! <3
have a great day :D
