After my attempts at the lightning, I found out Tom in the third year had been working on the same scene, so I am going to use his as a basis for my own work, and change the movements to what I think look right.
To me, the movement is a little too fast and I think it will be hard for the audience to take in what is happening that quickly. I realise that the lightning will take up most of the scene, but quick movements in the background will be off putting. I am going to try the scene on twos rather than single frames like Tom has done, and also add more rotation to the Guard's body.
Even if my version is not used, at least I can add it to my DVD at the end of the term.
