Abstract art was first developed in Europe. It falls into two major categories. Abstract art, in one way, is starting as the same image seen, and then not changing the realistic features of the picture. The second category is changing the picture purposely, giving the picture a look that has no relationship to the actual image. The artist's paintings have irregular, cell-like shapes that represente what they are feeling.
Many artists research the pictures they are going to draw.
They want to make the picture look as realistic as possible. Their research can take weeks, months, or even years. Abstract artists would have a feeling inside them that would make them want to draw something. They don't research it. They feel something, and draw it right then and there.
