What problems did I encounter from producing a swede?

While I produced my own swede of 'The Ring', I didn't encounter many problems. Our main problem and possibly only problem we had was the surrounding. With every shot planned with detailed drawings, camera shot and angle I knew what I wanted to film. However, the scene of the swede was set in a house which was difficult in the school surrounding. However, I improvised with old sofas in the back of sixth form, did a camera shot of just the two girls sitting on the sofa at an angle that wouldn't let the audience know it was a school surrounding.
