Arrrgh rethink in method..

I've run into a problem :( because now one of the images turn to a more square the shape rather than the rectangular snap of the others and when i parent them together, the rate in which the increase in size is different, meaning some layers end up covering up others. These picture explain what i mean.

As you can see the image on the left, the horizon is quite far away, and you can see a beach ahead of the children, however the image on the right explain my problem, because now the first image has zoomed in to quickly and the perspective has gone out of sync and now the beach or house don't even appear.

I am going to have to work a way around this
