Maquette for larger sculpture

I have been working on a couple of small sculptures and here is the second of them. The idea is to make these sculptures on a small scale and to then place them in the landscape using Photoshop. In the landscape they will be shown full size at several meters long. If the client is interested we might then have the maquettes scanned and full sized models made  in a foam of some sort. I have not done this before but it seems sensible and worthwhile if the client is at all unsure. This sculpture is a technical challenge as the area between the volumes is very tricky to reach and still requires considerable work.
