Should art be intentional and representational to be considered art?

Some art in the world today and in the past have been considered intentional because of the simple fact that it was used to help direct people or to show them how something is done. For example, the nomads, these were people who took different tools like burnt wood and flower petals and used them to create paintings on the walls of caves. They did this to show other tribe members what a bison would look like or maybe they did it to have a show to look at while they were eating the bison later on like a show. Art, now a days, has to have a shape or form for people to accept it. People like seeing stuff they can indenfiy with to have a feeling or a sensation of being close to the artwork. For example, George o' Keefe's paintings were of flowers but close up. Most people were shocked because they were use to seeing a flower from a distance, with all the petals showing and in bloom. If you see a drawing or a painting that looks like there is nothing but lines and bloches then you aren't quite using your imagnition to see what the artist has created.
Michalangleo did the Sixten Chapel intentionally because of course he was commissioned to do so unlike Piscaso, where he just painted subjects with different views and making it look almost like you, as the audience, seemed drunk. Artwork does not have to intentional or represent anything to have value put on by the unlooker. For example, if you have kids, they draw something it could be just a half way straight line and you'll love it put it up on the frige to show the whole world that your kid drew a straight line with a crayon. That's kinda what I think of Jackson Pollak's stuff. All he did was drible paint onto a canvas but he probably did it startically or could have done it like a child, just threw it on there and now it's famous all over the world. My personal definiton of art is what the artist draws or paints from his/her imagination or what they see as a beautiful piece of art and not what the public has to say about it. As long as you can draw or paint and you're happy with what you have done, that means no matter what they say you can stand there and have the personal sactifaction that you can do something that very few people can do and love it.
