What I have done

Here I have used the symbols and clicked on grime vector pack. Then I have reshaped the image so that it looks at the same shape as the mask I wanted to do.

Here I have added the title of the film festival.

Here I have used the rectangle shape to put on a background. and then sent in to the back. I then have added the stroke and changed the stroke colour to white. 

Here I have added the Middlesbrough College and UK Cinefest logos and added the websites of Middlesbrough College and UK Cinefest and changed the type face and the size of the writing to make it more to stand out.  

Here I have moved all of my writing so that it has been put in the centre of the poster
