Applied Animation: Animating the Space Bit

Continuing to work in After Effects I decided to animate the part where the camera zooms into a space cloud in which the Great A'Tuin is in and onto the discworld, as I thought I might as well get it out of the way whilst I have the time and I'm working in After Effects.

At first I found this task quite difficult at first, as I was having a lot of trouble with the camera and I couldn't get the key frames to work in the way I wanted them too. So I took a break and started from scratch with it. Whilst I managed to get the camera to work how I wanted it to, I have noticed that there is a small jump at the end when the camera finishes zooming into the Great A'Tuin. I'm not sure why it does this, as there is no key frame or anything that's causing this problem, so I'm not sure how to fix this.

However, I do plan on creating a fade at the end of this zoom to help it transition into the next scene a lot smoother, so it may be okay as it is. We will have to see.
