Graffiti, street art, Urban art, art, community art - I really like this piece of art because it has a lot of meaning behind it. It shows a blank wall that is being torn apart and behind it is so much color that is hidden.
Juxtaposition - Juxtaposition is a contrasting effect. In this artwork a tree and a bomb explosion are both being contrasted. This works perfectly because the explosion represents destruction but the tree shows life.
