I have decided to create an explosion using Aftereffects to finish the piece nicely, I thought this would be good after the camera has looked around the city and it would be a nice way to dive into the credits.
Below is a test explosion I have done.

I am quite happy with the look of this test explosion but it is extremely fast, this will need slowing down.
Below is another test explosion which is longer, this will give me an idea of whether to stick to this ending or just use a fade out into the credits.
Unfortunately I am not happy with this, to me it just looks out of place. I am glad I tested it otherwise I would have been worried about the ending. This means I will just fade into the credits.
