The First Draft of Questions

My group and I are making a film about the graffiti on our schools rooft it is call the roof top legends. but before we do that, we're going to make a trailer of our film. For our trailer we are going to interview the creator of the rooftop legends our school dean Jessie. I was in charge of coming up with the questions for this interview. I brain stormed a couple of questions that is to be answered in our film. 

Question #1:

when did you get into graffiti art ?

Question #2:

is graffiti something you've always been into?

Question #3

what gave you the idea to turn the rooft into what it is now?

Question #4

did the ideas for the graffiti come from?

I tried to avoid yes or no questions and questions that require only like a one word answer, I tired coming up with questions that he would be able to expand on and beginning to tell us a story.
