Working on an image.

At the moment I'm working on the ideas I mentioned earlier - childhood play and the perception of perspective - to hopefully create a maze-like image.
I've created a grid with rulers which I am stretching and snapping door/architectural images to. Then I cropped out an image of a girl, and am thinking of making varying levels of transparency in different versions of her. I guess I can work from left to right to create an architectural maze-like space...

But, I think I'm getting stuck. I'm going to rethink the perspective, and the way the image would look in the projection space, and consider tricks of perspective that will fit the space.
