how long is the essay? I have always been taught by my teachers to try use a whole lot of evidence.... approxiamately 3 or so techniques per body paragraph. Simply using only a camera angle for your whole body paragraph seems a little bit little, unless you smash out heaps of meaning and analysis from it. I would say that it would be ok to use another camera angle in your next paragraph but try finding something else.
I really like film analysis so feel free to ask anything (even though i might not be the best at it
) i would suggest talking about mise en scene, which can incorprate the use of camera angles, the distance and staging of actors, costume, acting and a whole heap more.
