New Cut-Out

I am working on a picture which combines methods I've used seprarately before: it is a cut-out in a deep frame, with four staggered layers. Previously when I have made these, I have made each layer a sillhouette, each cut from one sheet of card. This time I'm bringing collage and painting into it. Here are images of the two main layers on their own, and what all four look like put together at the moment.

I still need to work on the Pavilion, and one of the shop-fronts, as well as a few other little areas, before I can start putting this together.
