Site design and museum navigation

Here are the initial sketches for the site design as I envision it.

And here is the navigation design for the online museum.

Unfortunately the scans aren't perfect. However this is my initial idea of how the user navigates through the online museum, clicking and dragging to view the objects and areas. This may be subject to change as I am no longer certain that this type of navigation will be practical, but I am waiting to hear more advice from the project supervisors.
