Kieron,
Yes, unfortunately if you start to pay attention to the details it pulls out a lot of work.
There's 7 Compositions.
Bottom_ Up:
Background- you can completely replace it with simple image, video,....
Background Picture-simply replace with the resized original picture
FILM Composition-there's 2 Comps inside. you can delete lower one for the simplicity
2 Overlay Comps-again you can use only 1
Pict itself-......
Years Counter-looks complicate but it's very simple.
One Composition at the time, things gonna look less complicate.
Thanks for the comment and good luck!
