Is this atricle correct gramatically? Thanks (you have to switch the position of the subject and verb in a question. You can say it with the subject first, but only if you think the answer to the question is yes and you are only checking for verification. Furthermore, asking a question with the subject first and the verb second is usually only used in spoken English, not written English. I'm on the run so I don't have time to look at the full article, but I thought that would be a fun fact! : )  

GRAFFITI OR STREET ART

Street art sparks much controversy. Many people think that this kind of art is vandalism. In theory many of this type of art are a way to deface buildings, but in practice many of them became in viral art through the Net. However, I love it.

In the first place, street art is the best way to make up our city. Every year in Tudela, there is a street art festival which promotes many types of street art as pavement art, living statues, yarn bombing and graffiti. As anecdote, the first year that the Festival took place in Tudela, one sculpture was thrown out into the dustcart. In addition, it is a thought-provoking art that invite you to reflect about some aspects our social life. What is more, street art promotes our pedestrian and markets street. It seems to me that street art becomes our grey cities in a fun and colorful environment.

Last year, I went to Edinburgh to see the Edinburgh Fringe Festival and it was plenty of performances in The Royal Mille, all of them amazing. I improved my knowledge about actual state-of-the-art of social art.

To sum up, forgetting tasteless tags, I believe that we need promote and encourage all types of art. Not all art is in museums.
