Street Art

Today was my first art lesson. I was really excited because I've seen what the previous classes have been doing and I found it really interesting. Now I am glad I will have a chance to do it myself.
We are studying street art, and after a lot of discussion our class came to the conclusion that street art is legal arts, when you are allowed to do art in the streets in order to express your feelings or transmit a message.
Usually street art is very colourful, modern, urban and meaningful. Also, street art can be an urban intervention.
