First Animation in After Effect Z-Space

Yesterday we had a tutorial on how to use After Effects to navigate animation in Z-space/2.5D. This was particularly interesting for me given the direction I want to go with my project for this unit. My first attempt is below:

I am mostly happy with it but there are a couple of things which I would do differently in future; mainly that there should be more going on in the film to add foreground/background interest and emphasise the Z-space effect. Also, I think I should source some higher quality images. Apart from that I think it is a good first attempt.
