The girls were photographed at the Edinburgh Festival last year and I liked the way they stood together, as if sharing a secret. One is clean and smiling, the other has a more malevolent look and dirty clothes, hence the title. Sitting a helter-skelter at the end of a pier was a risk, but it needed a balance for the girls…and drawing a balloon in Photoshop was a challenge I had never tried before. It’s meant to be a fun picture and I hope that comes across.
